Hi all,
I noticed that our hosted-engine suites [1] often fail recently, and decided to have a look at [2], which are on 4.2, which should hopefully be "rock solid" and basically never fail.
I looked at these, [3][4][5][6][7], which are all the ones that still appear in [2] and marked as failed.
Among them:
- All but one failed while "Waiting for agent to be ready" and timing out after 10 minutes, as part of 008_restart_he_vm.py, which was added a month ago [8] and then patched [9].
- The other one [7] failed while "Waiting for engine to migrate", also eventually timing out after 10 minutes, as part of 010_local_mainentance.py, which was also added in [9].
I also had a look at the last ones that succeeded, builds 329 to 337 of [2]. There:
- "Waiting for agent to be ready" took between 26 and 48 seconds
- "Waiting for engine to migrate" took between 69 and 82 seconds
Assuming these numbers are reasonable (which might be debatable), 10 minutes indeed sounds like a reasonable timeout, and I think we should handle each failure specifically. Did anyone check them? Was it an infra issue/load/etc.? A bug? Something else?
Suites should be monitored by their respectful maintainers, the infra team doesn't have the capasity nor resources to monitor any new suite that is running in CI. Having said that, if a certain infra issue is reported, either its Lago, OST or infra issue, we'll of course do our best to find and fix the issue.
I didn't check the logs yet, might do this later. Also didn't check the failures in other jobs in [1].
