and then nothing.
steps to reproduce¶
A lot of job with same symptoms, e.g. take a look for all incompletes on https://openqa.opensuse.org/tests?hoursfresh=24&match=gnome-image but apparently only on openqaworker1
problem¶
H1. openqaworker1 has problems uploading the images
H2. The other error messages in the log about "permission denied" and such are related to the problem
suggestion¶
proper log messages about this.
workaround¶
maybe retrigger jobs until any other worker than openqaworker1 is hit?

ok, so it's a thing. How about we further improve our logging? Someone has suggestions? E.g. when size is zero, what should we output? Or check logfiles on the server?

In these 2 minutes we saw 1248 POSTs - so it was a quite busy time. But what is worrying me most: we saw 112 worker restarts due to rss limit. So I'm afraid these restarts happen too early - or too late.
This might also be related to the random problems we see on cavil. For reference: this is the restart code: https://github.com/os-autoinst/openQA/pull/1339

I raised the rss limit to 580.000 and restarted the job. Let's see

My latest findings for job 1039448 support my theory it's a mojo bug. I added debug for upload progress and what we see is a working
having a running transaction and restarting due to RSS limit:

The graceful restart restarted by the RSS limit is supposed to finish running transactions first

Updated by coolo over 7 years ago
ok, we know what it is. The mojo worker is restarted when it hits certain limits. But this restart is 'graceful', so it first finishes the current requests.
But the timeout for that is by default 20 seconds - and uploading a 8G file can take longer. So if the restart trigger is hit right after accepting the upload, chances are you don't finish in these 20 seconds and we fail.
I will set this limit to 800, but we will need to face workers that are in long timeouts and do not accept requests anymore. So possibly increase their number as well.
Updated by kraih over 7 years ago
To help with the problem of too many workers not accepting connections because they are shutting down, i've added
a new feature to Mojolicious. The web server can now
temporarily spawn a few additional workers as soon as an existing worker begins the graceful shutdown process.
The default is for up to two spare workers to be spawned, but that can be tweaked with the -s flag.

https://openqa.suse.de/tests/1076847/file/autoinst-log.txt looks exactly like that problem. Could it be a different problem even though the symptoms show up to be the same? How can we be sure? Some worker logs to check here? Or the logs from the web ui host at the same time?

Also https://openqa.suse.de/tests/1077066 and https://openqa.suse.de/tests/1077199 failed, reproducible problem, different workers.

It's a different problem though. The upload is done, but the rename fails.
