Nextcloud instance timed out / not reachable after update (?)

[details=“Support intro”]
Nextcloud version (eg, 20.0.5): 20.0.10.1
Operating system and version (eg, Ubuntu 20.04): Ubuntu 18.05.5. LTS
Apache or nginx version (eg, Apache 2.4.25): Apache 2.4.29
PHP version (eg, 7.4): 7.2.24

The issue you are facing: We updated from 18.xx to 20.0.10.1 two days ago. It was not-reachable for some minutes, but then worked again. Also, the 16 gig RAM got filled up completely, but got emptied some hours later. Today, it seems like it got killed completely. To be honest, I’m not completely sure if the update caused the problems. The logs don’t really give a clue what’s wrong. Input highly appreciated!

Is this the first time you’ve seen this error? (Y/N): Yes

Steps to replicate it:

  1. Update from 18.x to 20.x
  2. Wait some hours
  3. No profit :frowning:
    Not really sure if this made the problem appear, but we did’nt change anything else on the vServer.
