When checking stderr.log on all servers I see a couple of warnings/errors on some of them:
1. [STDERR] Unable to create lock file:  Disk quota exceeded
Failed to start up concurrent users module!

2. lsphp master: worker is killed by SEGV signal - increase PMEM limit

3. [STDERR] sh: host: command not found

Maybee you could give me some suggestions on how to check some of these and fix them?
I guess it can help others searching for the same aswell.

This is different warnings/errors on around 20 servers, I just picked a line from servers that gives these and was wondering if you could give some points on where to look.
And no, disk space/quota is not a issue on any servers.

If they are different issues, may just try the hints from them. Most of them are PHP issues, either missing some module (, or need to increate PHP memory limit, or other issue. the only one seems related to LSWS web server is
[STDERR] (DEBUG) lscgid:449136 Line #186 CRIU initial start = 20, it tell you CRIU related, Any issue for CRIU?
