We have a clone of draw.io. We have made some modifications to the UI for increased functionality. This works on localhost. We then did the Google Drive authentication process. But it was done on version 12.1.7 of draw.io. That integrated with google drive, except when re-opening a previously saved file.[Error with this version discussed here:https://stackoverflow.com/questions/62889536/no-access-control-allow-origin-header-is-present-on-the-requested-resource]
So, we ported our changes to the recent version of draw.io ,version 13.4.5 (https://github.com/jgraph/drawio/releases/tag/v13.4.5). Now, we get a different error. When trying to authenticate <screen shot of pop-up just before error> we get:
Login attempts failed.Please try again later <screenshot of error message>. When we look at developer tools, we see this

Any help to solve this issue will be great.

When I load my docker shiny app domain name in the browser, it crashes (greys out) and I get this "ERROR: [_parse_http_data] invalid HTTP method".
I have developed an web application that consists of a shiny app (has a login feature connected to an RMySQL database), a website and a mariadb database. I put them together in a docker-compose file and tested it on my local computer and it works fine. I then proceeded to deploy them in a Kubernetes cluster in GCE and that was also successful. I used cloudflare to install a ssl certificate for the shiny app domain (i.e. trnddaapp.com). Now when I load the shiny app domain in the browser it appends the https and loads the app successfully but after about a minute it crashes (greys out). I loaded the shiny app external ip with http and this doesn’t crash.
The closest solution I have come to is https://github.com/rstudio/shiny-server/issues/392 but there doesn't seem to be any other solution to my problem. I would be grateful if anyone help me resolve this problem.
This is the error message I get when I check with kubectl log [app pod name], I get this error:
ERROR: [_parse_http_data] invalid HTTP method
ERROR: [_parse_http_data] invalid HTTP method
ERROR: [_parse_http_data] invalid HTTP method
I expect the app not to crash when the shiny app domain (trnddaapp.com) is appended with the https.
Let's start with the analysis of the error message, it says:
[_parse_http_data]
So we know that your app is receiving something, but it doesn't understand what it is (it may be a malformed HTTP/1.0 or HTTP/1.1 or even binary data) then we have an
invalid HTTP method
Now we are sure it is not a HTTP/1.X call but a stream of (non recognized) data.
We now know is not the instance since it "deploys" and "delivers" the service, but something inside that is just breaking.
There are a few things that may be happening, since it runs in your local machine (where I am assuming it has access to more resources, especially memory) it may be an issue of resource allocation and that once ran in a container, it could be possible that it empties its allocated amount of resources and breaks (perhaps a library that is called in real time that uses a chunk of memory?) but we won't be sure unless we can debug it inside a container, so could it be possible for you to add a debug library that records your requests to see if it parses all of those and at some point in time it stops and why? I know a person from R-Studio created a httpuv that logs every request this can be done as in:
devtools::install_github('rstudio/httpuv#wch-print-req')
And after that, maybe share the output and see why the application is behaving like that and killing its own service.
I really thank you in advance, hopefully with those logs we may be able to shed more light into this matter.
Thanks once again!

I came across an error message when running Corda Enterprise. I was able to solve the error. But the link at the end of the error message caught my attention.
[ERROR] 16:28:02+0000 [main] internal.NodeStartupLogging.invoke - Exception during node startup: certificate key must be an instance of java.security.interfaces.RSAPrivateKey or sun.security.mscapi.RSAPrivateKey [errorCode=fnu1lw, moreInformationAt=https://errors.corda.net/ENT/4.0/fnu1lw]
This link is linked to a page that needs a login. And errors.corda.net is a dead link, too. What is the logic behind this link?
When an error occurs, the link that you see will do one of the followings:
try to find a Stack Overflow post that specifically answer to the error code (it is the fnu1lw in your case) and redirect to the page.
take you to the enterprise support site when it can't find a S/O post that is specific to the error code (as it was assumed that Enterprise customers would have a support contract).
Since you are running Corda Enterprise, so it takes you to the login page of Corda enterprise support.
ASP.NET WebAPI2 application on .NET 4.6.2, hosted on IIS on Windows Server 2016. From time to time, there is a lot (hundreds) of requests stuck for hours (despite the fact I have request timeout 60s set) with no CPU usage. So, I took the memory dump of w3wp process, along with sos.dll, clr.dll and mscordacwks.dll and all my project's dlls and pdbs from bin directory from server and used WinDbg as described in many blogs and tutorials. But, in all of them, they are able to directly see CLR stack by calling ~*e !clrstack. I can see CLR stacktrace for some Redis and ApplicationInsights workers, but for all other managed threads I can see only:
OS Thread Id: 0x1124 (3)

GetFrameContext failed: 1
0000000000000000 0000000000000000
!dumpstack for any of these gives just this:

So I have no idea, where to look for bug in my code.
(here is the full result:
https://gist.github.com/rouen-sk/eff11844557521de367fa9182cb94a82
and here is the results of !threads:
https://gist.github.com/rouen-sk/b61cba97a4d8300c08d6a8808c4bff6e)
What can I do? Google search for GetFrameContext failed gives nothing helpful.
As mentioned, this is not trivial, however you can find a case study of similar problem here: https://blogs.msdn.microsoft.com/rodneyviana/2015/03/27/the-case-of-the-non-responsive-mvc-web-application/
In a nutshell:
Download NetExt. It is the zip file here:
https://github.com/rodneyviana/netext/tree/master/Binaries
Open your dump and load NetExt
Run !windex to index the heap
Run !whttp -order -running to see a list of running requests
If the requests contains thread number you can go to the thread to see what is happening
If the requests contains --- instead of thread number, they are waiting a thread and this is a sign that some throttling is happening
If it is a WCF service, run !wservice to see the services
Run !wruntime to see runtime information
Run !wapppool to see Application Pool information
Run !wdae to list all errors
... And so it goes. When you do this again and again you will be able to spot issues easily
Sometimes when we open folder, Alfresco shows spinning wheel and never opens the folder. The log has below exception.

ClientAbortException: java.net.SocketException: Connection reset
at org.apache.catalina.connector.OutputBuffer.realWriteBytes(OutputBuffer.java:413)
If I curl the above URL or open directly in webrowser I am able to get the json response successfully.
I am using only Alfresco Share and not anyother client. The localhost:8080 is working perfectly fine in most of the cases except this one.
Can anyone please tell me what is the issue and why connection is closed or ClientAbortException exception is occurring?
Mostly this is an issue of timeout and you'll need active monitoring on your Alfresco & Share environment to see how Alfresco is running.
Easy check is to install some java monitoring or use Jmeter to load test the system and see how it responds on different load.
Mostly the outcome is more CPU/RAM for Alfresco :).
As Tahir Malik mentioned above, the issue is related to performance.
The ClientAbort error itself occurs when the client (in this case, Share) times out or the user cancels a download. The message on the log is type INFO. More details here: https://issues.alfresco.com/jira/browse/ALF-20349
If you are on SSO and using Alfresco Enterprise 5.2.3 or 5.2.4, there is a chance that you may hit a similar bug, which is discussed in the Alfresco Forum. However, this particular bug would not show the ClientAbortException.

I could not figure out if there is anything extra ordinary with this servlet. There is no init() method in this servlet and it extends HTTPServlet. Any idea what could be reason? I am using websphere server 6.0.x. How to get more debugging information in this case?
Well I don't know still cause of above error, but this is how it started working strangely:- i) Re-applied recommended fixes by IBM for my WAS version (especially there are IBM JDK upgrade related fix patches) ii) created a new profile of server iii) Install web application to new profile and it started working.
I don't think this is a product issue.
To debug this problem what i would suggest is to place a simple servlet (kind of Hello World) and deploy it to the server and see what happens.
initialization does not necessarily mean init() method alone.
If you have a static block in your servlet, if you have any variables that are initialized they would all be part of the initialization activity.
Look at the FFDC logs that were generated when this error occurred and that should provide you with clues.
As bkail mentioned, also ensure that yo have the latest fixpacks just to eliminate known problems with the product.
if the hello world servlet works, suggest you place hte servlet code here along with the SystemOut and System Err logs that correspond to this issue along with the relevant FFDC logs and i am sure most of us will be able to help you out with this
