Nextcloud is down one in a while and needs to be restarted manually

[opensourced]

A Nextcloud instance is down every once in a while (around once in a Week) and needs to be restarted manually. I have set the log-level to debug, however I cannot find any suspicous logs in the logviewer of the app.

The VM and also the application has enough RAM and CPU.

How can I trace this issue best?

Thanks for any help.

Depending on the usage pattern of Nextcloud, maybe the apache processes are all occupied at that point.
You can adjust the apache/mpm_prefork.conf via the filemanager and increase the MaxRequestWorkers there, then restart the app.

Thanks for the reply. I just doubled from 15 to 30. Lets see if this helps.
