High system resource usage #88
Comments
Hi! I'd say memory usage seems to actually be within normal - it's using "just" 1.5GB, the rest is the kernel that likes to hog memory for disk cache. Not sure about CPU loads, however. Was the machine unstable with a smaller machine configurations? (say 2-4CPU/2-3GB RAM?) What are the values from

It seems that there's also a Z-push authentication error when the services tries to get to the contacts for a user.
However, mail is pushed to the client and when the user pressed enter on the user/password prompt, all is well, until somewhat later when the whole thing repeats itself. |
I think maybe I should reinstall a fresh server, take backup and restore it. If I restore the automatic backup done by miab (with Duplicity), does it just bring the data, or will broken config also be transfered? |
For the Z-Push part, it seems to be broken both here (at least in Ubuntu 22.04) and in Mail-in-a-Box (the upstream project we fork from, also in 22.04) and will need to be resolved separately (As Z-Push does not support PHP 8). By curiosity, what OS are you running? Did you upgrade in-place? (for example, upgrade a working 20.04 or Debian 10 installation to Ubuntu 22.04/Debian 11 respectively without doing a fresh install). I think it won't really matter here, but in case it does... 😅 |

I ran the mailinabox script again, which upgraded me from 56.x to 60.2
Should I try a fresh server and restore the data, or should I just switch
the users to imap and caldav?

Btw did you try without "nextcloud desktop sync client" ? |
In die README.md file a spec of 1 cpu and 1 Gb of RAM is quoted, which is little enough. However, in a real world setup with 11 users (using activesync for mail and the nextcloud desktop sync client), even assigning 12 CPU's and 8GB of RAM seems inadequate.
I see a lot or activity from a process called "php-fpm: pool miab". Far too much as far as I am concerned...
What would cause this?
