Launch not created

[roma-diadiura]

Hi RP team,

we use reportportal more than 1 year. Our regression consists of 4 different java executions and after regression is finished we expect 4 launches to be present in RP. But sometimes (few times a week) we have only 3 launches, or even 2. In Jenkins job logs all is OK, all 4 java executions are finished successfully, no errors from RP either. But RP server API log is flooded with errors:

1. 'Launch not found. Did you use correct Launch ID' (full version attached)
2. 'Test Item not found. Did you use correct Test Item ID'

At first glance it seems RP server consumed a 'createLaunch' request, but the Launch itself was not created and no errors returned either. We are facing this problem for a few last months

Expected: if the launch was not created we receive a corresponding error message, or null instead of UUID.

We run tests on Selenoid using parallelization (6 threads)

@roma-diadiura do you run these launches in parallel on the same node?

@HardNorth Yeap, we've 1 RP instance and it was installed into Kubernetes via provided chart.
The tests communicate with RP server through com.epam.reportportal.junit5.ReportPortalExtension.java

Can you suggest a temporary solution, how can we check whether Launch was created or not? It will allow us to wait few seconds and try to create launch once more afterwards

[HardNorth]

@roma-diadiura I'm still have no idea what causes your issue, so I can't suggest you any solution. And it's still not clear for me do you run these launches in parallel or one by one?

[roma-diadiura]

@HardNorth
Every our regression consists of 4 launches:

1. junit_ui (6 threads)
2. junit_ws (6 threads)
3. junit_ui_one_thread (1 thread)
4. junit_ws_one_thread (1 thread)

The first 2 launches run in parallel (so it will be 12 simultaneous threads). Launch 3 starts when launches 1 and 2 are finished. Launch 4 starts when launch 3 is finished.
Every night we run up to 5 simultaneous regressions on different environments. This means RP server handles requests from, up to, 5 * 12 java threads

@roma-diadiura here I'm asking not about java threads, but about processes.
BTW, test cases from missed launches just disappear, or they go into a different launch?

@roma-diadiura do you use multithreaded configuration?

@HardNorth

here I'm asking not about java threads, but about processes.

I suppose you're asking about situation when multiple processes send requests into a single RP launch. We don't have such thing, 1 process (that has 1 or 6 threads) for 1 RP launch only.

BTW, test cases from missed launches just disappear, or they go into a different launch?

I'm 90% sure they just disappear, but it's hard to tell for sure. At least, we didn't spot any "lost" test cases.

@roma-diadiura do you use multithreaded configuration

To be honest, I wasn't aware of this feature. We don't have it's properties in reportportal.properties file, but if it is built in, by default, in RP5, then we use it unintentionally.

[HardNorth]

@roma-diadiura can you try adding rp.client.join=false to your reportportal.properties file?

[roma-diadiura]

@HardNorth

@roma-diadiura can you try adding rp.client.join=false to your reportportal.properties file?

Didn't work. During 5 days we have 34 regressions. 30 are OK (4 launches in RP), 4 are incomplete (2 or 3 launches in RP).

More likely it is JUnit 5 agent specific. Will se what I can do.
