Additional info

I get a ton of these entries and mails, over multiple months

joshtrichards commented 1 year ago

Can you provide the entries from your nextcloud.log from immediately to these memory errors?

Actually it sounds like you're likely getting these from cron, so can you run the cron occ commands manually with the -v parameter to see what's going on?

eickeh commented 1 year ago

Thanks for the reply. We uninstalled the mail app shortly after this ticket as we didn't use it very much. So I can't test anything manually anymore unfortunately.

But I dug out the logs from an old backup. They are probably not all directly related to the error above but seem nevertheless strange to me so maybe there's a connection. The error message above show up at 2022-04-21T12:10:29+00:00 again. I added some empty lines to group the messages.
