Hi all,
Have you seen something like the following in your worker-error.log? 20231018 07:44:06 instance-koha-worker-long_tasks: client (pid 3949888) killed by signal 13, respawning 20231019 07:21:26 instance-koha-worker-long_tasks: client (pid 4082852) killed by signal 13, respawning I found some discussion in a thread https://www.mail-archive.com/koha@lists.katipo.co.nz/msg30046.html Signal 13 would be a SIGPIPE I believe. At first, I assumed it was the connection between the background worker and RabbitMQ, but based off the RabbitMQ logs[1] that seemed unlikely. MariaDB is another possibility. Looking at its logs [2] and I see some timed out connections. I might monitor the connections between the background workers and the database tonight and see if it's related. It might also explain why it happens on my MariaDB system but not my MySQL system. Anyway, just putting out some feelers.
