Backups to S3 have been working for several years. Starting a month ago, I often get several notifications that the backup failed. Then it retries, and about an hour later fails again, so I get a second notification, and often up to six notifications in one day before it finally succeeds. The log f…

[תמונה] gerhard: Could you be running out of memory? I don’t think so. The server is overkill for our community with 16GB RAM. top shows 11GB free memory, and that hardly changes if I manually trigger a backup. I’ll check /var/log/syslog tomorrow for anything about memory, kill, or OOM. (Can…

I do have this in /logs. This particular warning did not coincide with the backup- I’ll check for that in the morning (backups are done at night).

Indeed, I was referring to the OOM killer. I completely forgot that there’s a memory limit for Sidekiq. Did increasing memory for Sidekiq help?

I believe that fixed it- want to see a couple more clean nightly backups to be sure. Will post here.

Yes, it’s fixed. You can close this topic.
