Description
Something strange is still going on with stuck builds. The encoder part is only writing to a file by now :(

Following Santi's advise I packaged and installed atop on openqaworker2 to get more details about this.
And the biggest time of tonight was:
04:51:07.5483 Debug: /var/lib/openqa/share/tests/sle/tests/qa_automation/patch_and_reboot.pm:24 called qa_run::system_login
04:51:07.5484 1457 <<< testapi::type_string(string='setterm -blank 0', max_interval=250, wait_screen_changes=0)
04:51:12.1727 1470 WARNING: enqueue_screenshot took 4.56 seconds - slow IO? (opencv: 0.01 - encoder: 4.56)
It should be noted that a parallel job had a similiar problem:
04:51:08.2241 1633 no match 190
04:51:11.9038 1633 WARNING: enqueue_screenshot took 3.67 seconds - slow IO? (opencv: 0.01 - encoder: 3.66)
Atop samples every 10 seconds, so I can only tell what happened around that time - but it doesn't look severe:

I can't spot a problem in what atop reports :(
There is not a single value in that sample that would indicate any level of problem. But I guess I need to increase the sample rate :(
Updated by coolo about 8 years ago
Increasing the sample rate at least shows that isotovideo is 100% CPU for 3 seconds

07:36:46.8803 19917 WARNING: enqueue_screenshot took 2.70 seconds - slow IO? (opencv: 0.01 - encoder: 2.70)
So I think it's safe to answer 'slow IO?' with no :)
Updated by szarate about 8 years ago
@coolo i think this could just be a sum between the time that the enqeue_screenshot took to:
- Scale the image
- Compare the new image to last screenshot.
- Write a screenshot that was not similar
- Writing the new frame
I would add to the enqueue screenshot warning, another variable to actually show the encoding time or at least the time it takes to write_encoder_frame, it should be there somehow

the problem on our aarc64 worker is clearly a different one
Updated by coolo about 8 years ago
- Status changed from New to Resolved
- Assignee set to coolo
So we finally understood the problem. What you can see in the atop report is 1.3G dirty buffers - and in that situation flushing files (videoencoder.log) requires the process to wait. So we avoid every IO in this loop - but only async write PPMs to the videoencoder
