observation¶

Accessing https://openqa.suse.de/tests/overview?distri=sle&version=12-SP2&build=1204&groupid=25 yields an error "502" after some time.

from /var/logs/openqa on o.s.d:

Steps to reproduce¶

• access https://openqa.suse.de/tests/overview?distri=sle&version=12-SP2&build=1204&groupid=25
• wait until page times out

Problem¶

I see the very long query time (see observation) but no other obvious error message in the logs. I am trying to reproduce this locally and it looks like this is possible. The very long query from above also appears (twice) plus a subsequent

Took 12.04192710 seconds executed: SELECT me.job_id, me.result, me.soft_failure, COUNT( id ) FROM job_modules me WHERE <super_long_job_list>

and finally the request is finished without timeout when run locally after 111.849923s. Remember to also see parent task #10960. The slow rendering is not because of any change since 97b8d92 but the database changed its layout or content since then or something in the data of new builds is very different from before, e.g. many more jobs for external reasons.
