Changing problem time limit in running contest causes error

[mkfuron]

Description of the problem

I created a "Private Contest" with only jury users to use for importing problems. After importing a problem, I go to change the time limit from the "Edit Problem" page. When I select "Save" I get the following error:

"500 Internal Server Error
Sorry, an error has occurred: Internal Server Error.
Please contact a staff member for assistance.
EventLogService::initializeStaticEvents no response data for endpoint 'contests'."

When I look at the problem page it looks like the time limit was changed to the new value.

Your environment

DOMjudge 9.0.0
Fedora 42
nginx 1.28.0

Steps to reproduce

1. Import a problem into the contest.
2. Go to the Problems page as an administrator.
3. Edit the problem time limit.
4. Save the revised problem.

Expected behaviour

Time limit changes and problems page appears.

Actual behaviour

"500 Internal Server Error
Sorry, an error has occurred: Internal Server Error.
Please contact a staff member for assistance.
EventLogService::initializeStaticEvents no response data for endpoint 'contests'."

This problem also occurred when I added a PDF file as problem text to an existing problem.

I tried to reproduce this by:

• Creating a contest.
• Marking it as not public and not open to all teams.
• Adding only my jury team.
• Edit the timelimit of a problem.

But for me it works.

Could you maybe (in Slack DM) send a dump of your database? I think that would help in finding the issue in this case.

I got the dump from @mkfuron but could not reproduce it. He tried himself with that dump on a local machine and could also not reproduce it anymore. I'm not really sure how to move forward...

Is there anything in the php-fpm log, maybe the server was under powered so lost some children halfway a request?
