On Plesk for Linux mod_status is disabled on upgrades to improve Apache security. This is a one-time operation that occurs during an upgrade. You can manually enable mod_status later if needed.
I did found this:

But I still don't quite understand how a distinction can be made here between server and user backups.
Hey! I would like to automatically download the last two complete Plesk backups and all associated incremental backups via shell script (from an external backup server). I explicitly do not want to use SFTP, as no incoming connections are allowed on the backup server.
Is there any useful...

I was just able to reproduce it this way too, so the task limit doesn't seem to be the problem:

Analysis Commands
cat /proc/sys/kernel/pid_max

Output: 4194304
This is a very high limit, meaning the system allows up to 4.19 million simultaneous tasks.
It’s a kernel-level setting and not a practical limit for...
It seems to have something to do with the cgroup limits? I still have the error with Plesk updates.
