This always happens overnight, usually after midnight, though one time it was
around 10:40. I don't see any crontab entries that correlate. And the after
midnight issues don't always happen at the same time, so it seemed unlikely
that it was a crontab job that was causing it
I finally looked at the host (rather than the logs of each container) and
realized that the oom-killer was killing django-admin. As a temporary
workaround, I've limited memory on the mailman-django-uwsgi container to 4 GiB
(though, since I just did that this morning, I won't know until after midnight
(presumably) if it worked or not), and set the RestartPolicy to always.
The above suggests it's one of the Django daily jobs that's hitting the
OOM. These jobs are
appname - jobname - when - help
--------------------------------------------------------------------------------
django_extensions - cache_cleanup - daily - Cache (db)
cleanup Job
django_extensions - daily_cleanup - daily - Django Daily
Cleanup Job
hyperkitty - orphan_emails - daily - Reattach orphan
emails
hyperkitty - recent_threads_cache - daily - Refresh the
recent threads cache
hyperkitty - sync_mailman - daily - Sync user and
list properties with Mailman
I don't offhand know which of these might be a memory hog. Further, if
one of these dies for out of memory, I don't see it affecting more than
that job, not the entire service.
