On Linux, the RSelenium/Selenium seems to be behaving erratically. I start the server manually and it seems to start up fine. Sometimes I am able to connect to it from my R session and other times I get an error. I cannot yet pinpoint the cause: the same script seems to work sometimes and not other times. Any ideas?
Here is the output from starting the server:

The error I receive in my R session:

Please ensure a Selenium server is running.Error in queryRD(paste0(serverURL, "/session"), "POST", qdata = toJSON(serverOpts))
Other times, running the exact same script everything proceeds successfully. It could be a difference of what computer node actually executes the script but I cannot tell what the problem is when it will not connect.

# running selenium
system("java -jar selenium-server-standalone-2.44.0.jar")
I faced same issue and try to run above code. Finally know that there only support 1.7 but not 1.8 as time being. You might try to download jre7 and jdk7.
I faced the same error in Mac, but I noticed that due to security settings the system does not let me to run the file with that piece of code. I downloaded the selenium standalone file and using control key I single-clicked the file and then from the menu I chose the open. Then the problem get solved.

I have started to face this problem. While trying to connect, I am facing an error stating that my traffic-manager version is 2.1.5 and it should be at least 2.4.5.
"telepresence connect" command checks for new versions and modifies it if there is any new version exists. So I am thinking that started to create a problem. Because I was using it as normal.
When I check the connector.log file these two lines create the problem.
connector/session : Existing Traffic Manager 2.6.5 not owned by cli or does not need upgrade, will not modify
connector/session : failed to connect to root daemon: rpc error: code = Unknown desc = unsupported traffic-manager version 2.1.5. Minimum supported version is 2.4.5
So somehow I have two versions now while checking for the update it hits 2.6.5 but while trying to run it tries with 2.1.5. Trying to uninstall telepresence but it also faces the same problem and I couldn't locate and delete traffic-manager 2.1.5. My OS is Windows 11.
Because of that, I am kind of blocked with my tests. Any help will be well appreciated. Thanks!
After asking the question, a new version arrived, if anyone encountered this problem, please update telepresence to 2.6.6. It is fixed now.
I downlaoded the Infinispan server package from Infinispan offical website. To create a local cluster and test out. The server starts perfectly fine, but it blows up when I try to create a user using the offical command as follows: ./bin/cli.sh user create admin -p "password".
I get the following error no matter what:
Error: Could not find or load main class Cache.infinispan-server-13.0.8.Final.boot.infinispan-server-runtime-13.0.8.Final-loader.jar
Caused by: java.lang.ClassNotFoundException: Cache.infinispan-server-13.0.8.Final.boot.infinispan-server-runtime-13.0.8.Final-loader.jar
I know it has to do with my processor arch, solely because I've tried exact same downlaod on an M1 MacBook Pro and Windows which works perfectly fine!
Please any help would be appreciated!
I'm getting the following error message when I try different operations such as installing an application to a Firefox OS simulator:
Operation timed out: installing and running app
I've tried versions 1.3, 1.4, 2.0 of the simulator - all have the same error.
The application does get deployed to the simulator and runs. However, console.log() output does not get displayed in the WebIDE Console.
For the location of the error message, see the screenshot below
My Firefox Version is - 42.0a1 (2015-07-16)
This is running on Ubuntu 14.04 x64.
When I click on the Troubleshooting link, I can't find any tips for troubleshooting a simulator.
Any ideas?
The steps I followed were:
Open WebIDE. Terminal output:
* daemon not running. starting it now on port 5037 *
* daemon started successfully *
Start Firefox OS 2.0 simulator, simulator displays. Terminal output:
console.log: Connection status changed: connecting
console.log: Connection status changed: connected
Project >> Open Packaged App, and select my application. No Terminal output.
Project >> Install and Run. Application displays on simulator. Terminal output:
console.log: Installing app from /home/snowch/tmp/Scratch/myapp/hw_chs
console.log: Starting bulk upload
console.log: File size: 14253
console.log: Bulk upload done
After about 10 seconds the error message is shown as per the screenshot.
Update
The jconsole error messages:
Simulating large screen devices (Operation timed out: installing and running app)
Simulating small screen devices, after clicking on the spanner (Operation timed out: opening toolbox)
It looks like you've run into several bugs with older simulator versions.
For the issue with app install when the screen is set to Via Vixen, I filed bug 1186929. For myself, it only reproduced on 2.0, but please comment in that bug if you have more specifics.
For the "opening toolbox" issue, I believe that is a compatibility problem that needs to be resolved with older simulators, which is bug 1161131.
I tried asking several times in the comments above if you ever actually see the toolbox appear, or if you just get error messages. It would still help to know the answer here.
As a workaround, you should be able to use Simulator 2.2 or later to avoid these issues until they are resolved.
I have installed Couchbase 2.2.0 for Windows 7 64 bits. I installed it using the default options. The service gets installed and I can stop/start or restart it without errors. However, I cannot connect to the management console on port 8091.
I've found some posts on how to deal with this but they all relate to older versions of couchbase and reference files/options I can't find in version 2.2 (for example this post : Unable to connect to http://localhost:8091/index.html).
When I try netstat -an -p tcp I can't see any service listening on port 8091 so I suspect something goes wrong during startup.
Looking in the couchbase log in /var/lib/couchbase/logs I can see some errors but they don't make sense to me.

The windows firewall is running but, since I installed the same version of couchbase on another machine with the same Windows version without troubles I can't imagine that the firewall is causing this trouble.
I'm out of options though, I have no idea why I can't get this to work.
In the meantime, I have uninstalled 2.2 and tried falling back to 2.1 (with the same result) and moving forward to 2.5 (with the same result). In all cases I turned of antivirus software and stopped the Windows firewall to eliminate this cause.
Thanks to the nice people at Couchbase.com, the problem has been solved.
Please refer to :
https://www.couchbase.com/issues/browse/MB-10245
https://www.couchbase.com/issues/browse/MB-8760
The solution is to reinstall couchbase in a location without spaces in the path. Due to a bug, spaces in the installation path lead to trouble.
UPDATED: Took everyone's advice and decided plone.app.registry and 4.1.1 were not the issue, question is, what is? Where can I find the error logs in binary installer?
symptom: can't add content types (under Add New... folders, pages, news items, etc. -- hangs on save, more specifically my portal_factory is unable to validate and move the content to ZODB).
had same issue using both unified (4.1) and binary (4.1) installers
environment: mac book 10.6 Snow Leopard 32-bit
When I run buildout I see no errors:
2012-05-08 18:13:34 INFO ZServer HTTP server started at Tue May 8 18:13:34 2012

When I create a new site in Plone, Terminal says: http://pastie.org/3882025

That's not an error - that's what happens whenever you start up an instance with a new Data.fs file. If there's no Data.fs.index, or the .index file is inconsistent with the Data.fs, the existing one is ignored and the index is rebuilt. It means absolutely nothing on a new install.
There must be more information than this in the log.
Fixed this issue by following this post here: http://plone.293351.n2.nabble.com/Add-new-Plone-site-creates-site-with-JS-problems-4-1-4-tt7547774.html#a7555663
Basically, had to go to javascript registry, save, empty cache, restart browser, testing in Chrome only.
