I just updated to nextcloud 22 on my gentoo linux pc prior to updating on my linux shared hosting.
My local pc is now generating cron emails ‘running maintenance(#)’ every time, as in every 5 minutes. The # is a number, I guess how many concurrent maintenance jobs are running.
This never used to happen and I suspect it’s some sort of debug message and cron doing it’s usual thing of emailing cron output.
Is there some configuration option I have to tweak or is this an issue?
EDIT: It appears it was simply a ‘long running’ job, the emails stopped after about 1.5 hours.
