Getting occasionaly Exit code -10 on agent node

Hello dear community,

I ran into very frustrating issue, when TestComplete occasionally returns Exit code -10 (Unable to create a user session) to Jenkins from my agent node.

On our master (Built-In node) machine everything works perfectly. We have this problem only on agent node.

To be clear it is not a permanent problem. Sometimes the session is created and TestExecute performs the tests correctly and returns results correctly. But sometimes it returns Exit code -10. There was no change at all at agent server, nothing happened there, neither in Jenkins. After this happens, every other test which we run on agent node fails with Exit code -10. After I restart the the agent (Windows) server, TestExecute starts working correctly again and everything is perfect, but then after few days after tens of successful builds, this issue happens again, and suddenly we are receiving Exit Code -10 again. We contacted out IT support team to check the Windows Events log, but they cannot see anything suspicious. True that, we can see the logins and logouts from Windows with the dedicated automation user, but there is no reason in logoff message, it seems like it is a regular log off. I tried also to reinstall the TestExecute on agent node, but it did not help. This issue is present only on agent server, master server does not have this issue.

Any help would be appreciated, because I dag up the whole internet already.

Thank you.

Stefan.
