Hi all, A couple weekends ago I upgraded our Koha instance from 22.05 to 22.11, and I'm having trouble with the background_jobs processes becoming zombies after a very short amount of time, necessitating a reboot. I suspect it's a misconfiguration on my part, so if someone can shed some light I'd really appreciate it! The first symptom was our MARC imports getting stuck at "import queued", and after some digging (and thanks to the thread in this list with the subject of "Background job / Staging MARC import stuck at 0%" I found I was entirely missing the <message_broker> section in our config, so I added this: <message_broker> <hostname>localhost</hostname> <port>61613</port> <username>guest</username> <password>guest</password> <vhost></vhost> </message_broker> Which seemed to resolve it, but now I find that the background_jobs processes are going zombie after processing only a few jobs. Here's some info from the rabbitmq log after restarting the server: =INFO REPORT==== 18-Apr-2023::12:23:46 === node : rabbit@ccflskoha home dir : /var/lib/rabbitmq config file(s) : /etc/rabbitmq/rabbitmq.config (not found) cookie hash : ojvkUE6eUtku7kHlx3uiFg== log : /var/log/rabbitmq/rabbit@ccflskoha.log sasl log : /var/log/rabbitmq/rabbit@ccflskoha-sasl.log database dir : /var/lib/rabbitmq/mnesia/rabbit@ccflskoha Is it problematic that /etc/rabbitmq/rabbitmq.config is missing? Anything else I should be looking at? We're running on Ubuntu SE 18.04 if that is helpful. Thanks much!
