I am learning tosca and currently we are trying to run a regression test suite for a legacy Java Swing application.
My Test suite contains 4 modules (in JTree) and it is getting failed while clicking a node.
The Error I received on the module is,
at.tosca.javaengine.common.exceptions.ControlException: node or
node-path not found! Detailed information contained in

NOTE : The same Test suite is working in some other machine and not here. Both are same operating System.
This is a bit confusing.
Looks like you are connecting to a JTable and then trying to select a node? Are you sure Tosca is finding the correct control on both machines? (Index=3 does not sound like a stable identification.
The problem was TOSCA is faster than our application :)
Meaning: The frame was not loaded at the time when TOSCA was trying to scan the next page causing the error, the specific node was
not found.
Solution: I added a TBoxWait with extra seconds, after that this is working fine.

I'm trying to open the Artifactory Users Management page, following the Admin->Security->Users tab.
Then I'm getting the following error:
Any idea of what might be causing it? Also, which log I can check this? Couldn't find anything yet.
The server error generally indicates there is problem fetching the user details from Artifactory. This can happen due to any of the following reasons:
when you have a high volume of users and the request is timing out.
There is a chance that you might have created a username with a
special character which is not allowed (using the REST method or some
other method)
There is an issue with the backend database
And the best place to troubleshoot is to first check the request log a good valid entry looks like below:
20200715164402|104|REQUEST|165.225.104.49|admin|GET|/ui/users|HTTP/1.1|200|0
Next check the artifactory.log file for java stack or check catalina.out under tomcat/logs directory.
I'm trying to create a hologram that is shared among multiple Hololenses by following Microsoft's Holograms 240 tutorial at https://developer.microsoft.com/en-us/windows/holographic/holograms_240
The network connection is working fine, and I have all the correct permissions in my project settings. The issue is that aside from a rare occurence, the call to WorldAnchorTransferBatch.ExportAsync() will fail with a SerializationCompletionReason.UnknownError and print out "Failed to world lock serialization failed"
I haven't been able to find any information about this error in my searching. Does anyone know what the cause of this could be?
Sometimes when we open folder, Alfresco shows spinning wheel and never opens the folder. The log has below exception.

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 have a Loadrunner Test Scenario, here is the snapshot for it:
after opening my Test Scenario with Loadrunner Controller, I click then the "Start Scenario" button, the Scenario must run for 2 Hours, but it stops after 1 minute, and get the following Error:
Failed to stop Service Virtualization.
Failed to start Service Virtualization.
here you can see the error snapshot:
to increase the size of the snapshot please: Ctrl++
It seems that you have unwittingly activated an integration with HP Service Virtualization (or SV for short), without having SV installed on the same machine. In order to remove it, open the SV configuration dialog and uncheck all the entries.
I solved the problem with a lot of effort.
the problem is, when you have test scenario, which worked before, and you try to remove some script (groups) of the scenario,after that the test scenario will not work, what I've done, is I created from scratch a new scenario with the same test scripts, and voila it worked, I hope everyone will pay attention at that in the future
I have a website which has been up and running absolutely fine for about 8 months now. It's running .net 4 intergrated mode.
Recently i've started to get some "random" w3wp.exe crashes, and after 5 of them, IIS rapid fail protection kicks in and I have to manually login to the server and start the application pool again.
Here's what the event viewer says for the Error:

That nlssorting.dll seems to crop up a lot but I can't seem to find anything online related. The only thing I can find which matches my error is here, but that doesn't really help me.
I'm completely stumped as to where to go from here to fix this. Here's what I've tried:
Loading up IIS log files and trying every request from about 30 minutes before a crash, and none of the pages cause any errors.
Searching my code for any recursion which might cause a stackoverflow, but there isn't any
trawling online for ANYTHING that might help
Has anyone else ever had any problems with nlssorting.dll ? Can i get some more information from the .wer file that might help me pin point where this is happening?
Thanks in advance for any help!
UPDATE
I was using a 3rd party DLL, which was causing a stack overflow exception (0xc00000fd)
After more investigation, it was only happening after a certain chain of events happened - hence the "random" in the title. Removing the DLL fixed the problem.
We had the same problem with one of our sites. Using SVN we tracked it down to a method that was scaning for images within a folder.
I modified the code as follows:
Checking array length of scan results to be > 0 instead of == 1
Adding CultureInfo.InvariantCulture to all Int32.ToString() calls
After this we no longer experienced the error. The exact reason is still unknown.
I believe that none of the above points should make a difference in our environment. I believe that the problem could have been, people modifying image files and folders while the image scanning method was called.
I hope this helps somebody.
For anyone who's curious, this is a PITA to debug. Here are three reasons rumored for this to happen:
(1) Stack overflows, as in the original post.
(2) Too much CPU / memory usage, which becomes obvious and rapid fail protection closes the process.
(3) Unable to respond to pings / requests due to application hogging resources, but in a way that rapid fail protection deems appropriate to end the process, not explicitly because of either (1) or (2).
Our solution was to add manual log tracing in the production environment until we eventually found recursion which was leading the application to be stopped by reliability services (for inability to respond to pings, or process randomly crashing) rather than throwing an in-application exception.
I had the issue where w3p would throw an unhandled error as soon I spun up the site\api URI from the web browser, then it would crash.
I was able to pinpoint what part of my code was causing it in my case it was in the Owin Startup class and I was reading some configuration records from a database but prior to that it gets the connection string from a configuration file outside of the web app directory.
I checked the ownership of the folder it showed my account but apparently the subfolders were not owned by me so I set ownership to me again, clicked OK to allow permissions to traverse the objects and voila bye bye w3p error and the API loaded.
So in my case it was an access denied error on the folder \ file that contained the connection string.
