I'm trying to debug an air app. Something I've done probably no less than 1000 times. I know I've fubar'ed some config on my machine. But for the life of me I can't figure out what.
Things I've tried:
Changing the SDK (4.6, 4.10, 4.14)
Reinstall Flash Builder 4.7
I can see Flash Builder listening on port 7935
Flash Builder just times out trying to connect.
Ideas?
Figured it out…
We have to edit our host files at work to spoof different hostnames and I had removed this entry:
127.0.0.1 localhost
After putting that back Flash Builder was able to connect fine.

I am using VS2015 and I am trying to run a website application, but every time I run the project I can't load the IISExpress because it says that the port 80 is in use, I run the Tcpview.exe from SysInternals to see who was using the port, but seems not to be in use. I found some related threads saying that can be a problem with the antivirus, I am using Symantec.
Here are the properties of the project, as you can see I tried to change the port manually, but it didn't worked
See the picture below
It is something weird, if the website is inside a solution, seems that it doesn't load correctly the application and all the time the port is ins use. I solved it using this approach

I just loaded directly using the Visual Studio Option-> Open-> Website and removing the entries from that the post below advice
We are evaluating moving from ESXi standalone hosts to Cloudstack. I've used the documentation here http://cloudstack-installation.readthedocs.org/en/latest/qig.html to do a single machine setup on a fresh instance of CentOS 6.6.
Installation is complete, however I cannot add any ISO templates. When I add any version of CentOS 6 (tried 6.5 and 6.6 minimal) I get the cryptic "Timeout waiting for response from storage host.". I tested the two NFS shares that are setup in the install and they can both be mounted with no issue.
Are there logs that might give me more information as to what is going on? From going through /var/logs/cloudstack all I'm getting are a pile tomcat and java logs with nothing obviously referencing what I'm trying to do.
I found the problem. Apparently their firewall configuration is just wrong (I was iffy on it originally but decided to stick with it). Stopping iptables allows the image to be uploaded, I assume restarting the services will re-add the firewall rules we DO need.
I have an issue on exported build release from Flash Builder 4.6. The case is when I run it on the IDE(Flash Builder 4.6) it works fine, no issues encountered, it never crashed but when I exported it for a release build and run, it crashes to a certain module/view. The view/module where the AIR app crashes has multiple remote object calls (minimum of 5). I have noticed that when requesting multiple remote object calls(like 5 remote calls at a time) it crashes. Is the remote object causes the crash? Please help me out on this guys, any idea will be much appreciated.
Thanks

I bet it's a security issue that you worked around when invoking the application from the ide. By default, Flash Builders working directories are marked as "secure", so you don't get any security issues. But when working on the live system, you might need to have a corssdomain policy.
Also: i suggest to use the Thunderbolt logger with the logging framework. This allows you to get log informations straight into your browser's console.
UPDATE + SOLUTION ===============================
Sorry to be posting the solution here instead of in a comment, but something about my work's filtering doesn't allow the comment functionality to work for me.
I ended up using the -b 0.0.0.0 property in jboss to bind to all addresses, so I could try accessing machine A's server with machine B as the client, and vice-versa. I found that it always failed to load when running on machine B, whether or not I was connecting from A or B.
I started wireshark on a windows machine on the same network, and observed the TCP connection that was loading the webpage. I saw that the request for the .swf in the cases where it failed had a content length of 2 million or so, and when I right clicked the wireshark logs and selected "view conversation" or something like that, the size of the total conversation to get the .swf file was only 130,000. Looking at about:cache, that was about equal to what it ended up caching before saying "Done" on the page.
I ended up finding that there is a bug with the useSendFile property. (http://community.jboss.org/thread/148651?tstart=0). This causes it to only send part of the file if you are running low on kernel memory. Using useSendFile="false" in our server.xml has seemed to resolve the problem.
==================================================
Original Problem
I have a JBoss (5.1.0.GA) application server. I am using GraniteDS to connect between the application server and the client. The client side is flash-based.
Granite DS requires the use of the APR library (apache native library), so I am loading it. I see in the JBoss logs that it says it loaded the apache native library just fine (version 1.18, though I've also tried 1.20).
The issue is that when I have it so the APR library loads successfully, then the Flash side of the application does not usually load. I'll have to hit refresh a bunch of times and eventually it will usually load, but normally I'll see either a black webpage that says "Done" or the loading progress bar never move. Only by repeatedly hitting refresh will the page load. It will load eventually by hitting refresh enough, but it is not consistent and this obviously will not work for our clients who have to clear their browser's cache every time.
This problem only exists on Solaris, our application works fine on Windows. We've tried multiple patch-levels of solaris, and have verified with the "ldd" command that the library that needs to be loaded has all its dependencies there.
We've verified it isn't our swf file's size by testing:
1) Our regular SWF (1660 kb).
2) A random large-ish SWF (950 kb).
3) A small SWF with one label component that says "Test" (277 kb).
All 3 were unable to load when JBoss was also loading the native library, and loaded just fine without it. We need the native library to load successfully for Granite to connect between the client and server though, so not loading it isn't an option (unless there's some way to use the NIO connector with JBoss, but it appears unsupported).... if there is a way to use the NIO connector then we shouldn't need the APR library.
Has anybody run into this before? Anybody have any ideas or recommendations?
Have you tried the jboss native libraries for Solaris ?

Related to a previous issue that I thought was resolved and actually isn't...
My Visual Studio 2008 installation may be a bit messed up, I think.
When my ASP.NET project is set up to use VS Dev Server with a fixed port, I get the "Port in use" error described in the linked question.
When my project is set up to use a random (auto-assigned) port number, it works, but it launches the browser using a port number 3 less than the actual Dev Server port number (e.g. if the port number is 1903, the browser launches to http://localhost:1900/)
If I make changes to the project settings, they do not "take" until I save and restart Visual Studio.
Any ideas how to track this one down?
Thanks!
I had a similar problem which hit my 2 main machines at the same time. On investigating I found it to be related to the Eset personal security (guessing a recent update messed something up). To solve it I excluded VS2008 from the active browser filtering - this is in:
setup -> advanced firewall setup -> antivirus & anti spyware -> web access protection -> HTTP -> webbrowsers
Deselecting vsdev in here fixed the problem - interestingly enough disabling the firewall and antivirus / antispyware did not solve the issue, so it is worth looking for a similar setting if you are running different security software
First try to kill all "WebDev.WebServer.exe" processes.
In Solution Explorer, click the name of the application.
In the Properties pane, click the down-arrow beside Use dynamic ports and select False from the dropdown list.This will enable editing of the Port number property.
In the Properties pane, click the text box beside Port number and type in a port number.
Click outside of the Properties pane. This saves the property settings.
Hope this helps
I do absolutely agree with Macros' answer. Just want to share solution for Eset Nod32 v5
In ESET NOD32 v5 to allow Visual Studio to run Development or IIS Express server you must uncheck Visual Studio in Nod32 Advanced Setup => Web and Email => Protocol filtering => Web and email clients
Weird!
The port number is stored in the .sln file. So, I'd blow that away the solution file first, re-create it and see what happens. If that doesn't help, I'd then move onto the web.config file and blow that away and start again too.
I also encountered the same error message:
Unable to launch Visual Studio development server because port [xxxx] is in use.
However, I do not have ESET installed. Instead, I had recently installed GlassFish server on my machine and that was causing the problem. Therefore, in Windows Task Manager, I killed the process it runs under which is java.exe and it fixed the problem.
This also applies to Visual Studio 2010.
And there is more to it.
Symptoms:
A Web (Services) project is configured to run at a specific port, e.g. 10080.
After a while Visual Studio compains “Unable to launch the Visual Studio Development Server because port ’10080′ is in use”
The reason is still unclear. It might have something to do with the webdev server crashing.
Restarting the pc doesn't solve the problem.
Netstat doen’t show an entry for the port 10080
Manually startin WebDev.WebServer40.exe at port 10080 works fine.
Since I'd like to start from within Visual Studio, I moved to port 10081, then to 10082, and today to 10083. I’m running out of ports.
Solutions that did not work:
Restart Visual Studio
Tweaking Trendmicro security settings (couldn't access them)
Disabling Forticlient antivirus/firewall
Workaround that DOES work:
Configuring my project to manually start the server
Right click the project, choose properties
Click the tab "Web"
Pick for start action "Start external program" and point it to Webdev.Webserver40.EXE
(for me: C:\Program Files (x86)\Common Files\Microsoft Shared\DevServer\10.0\WebDev.WebServer40.EXE)
Command line arguments: /port:10080 /path:C:\Solution\Project
Working directory: C:\Solution\Project
Under servers check "Use Custom Web Server"
Do not check any debugger checkbox
Side effect: my project thinks break points are not getting hit. ("no symbols loaded"). Turns out they work like they should.
I hope anybody ever finds a definitive solution, but up until then this workaround does the trick for me.
To solve your problem, just restart your PC. I've had the same problem, I did the same thing.
