The Funkwhale server goes down and have to restart it. The problem occurs a few hours after I’ve uploaded a new podcast file. After I’ve restarted the server it remains up till I’ll upload a new podcast file.

Here are the logs: hastebin

OOM = Out Of Memory

It could be a memory leak due to the file upload, but also due to another app. Which apps have you also installed on your server?

I have Peerube and Mastodon installed but the problem occurs only after the file upload.
