Selenoid UI goes down intermittently on SLES 15 SP4 VM but container stays up and no discrepancy found in logs. #537

Closed iamgopalan closed 1 week ago

Selenoid UI goes down intermittently on SLES 15 SP4 VM but container stays up and no discrepancy found in logs.

  1. Everything is working fine and suddenly the selenoid url will stop working and when I inspected network from browser console I see failed to load response data: no resource with given identifier found issue but if I log inside VM and check docker o/p everything looks good.

  2. The only way for me to resolve this issue is I need to reboot VM and once VM is back online I can see that selenoid UI is working fine ?

  3. How to debug this kind of issue further as selenoid logs does not capture any discrepancies or root cause of this intermittent issue ?

  4. We never know what users can do or do not have any control on what actions they do on selenoid UI which is causing this intermittent issue. Please advise how this can be root caused ?

Attached logs for detailed debugging and analysis.

How do i differentiate whether its a OS level issue or selenoid container issue and why OS level problem causes intermittent issues for selenoid and how to prove this using logs and rectify same permanently ?

@iamgopalan we don't have any experience with SLES. Anyway this does not seem to be related with Selenoid UI, because you have a networking issue.
