Just discovered something that may help to debug:
It does not happen with a simple “Hello World” bash script instead of
the Check MK Agent.
It does not happen when the Encryption of the Check MK Agent is disabled.
It happens when the Encryption of Check MK is enabled, which should be
AES 128/256 output.
I wonder if the MK agent does some tricks like locking the memory when
encryption is on and then does not properly release its resources?
Just to ask the obvious: The slice(s) themselves are empty, i.e. the
check-mk agent process has exited (successfully)?
What's the status of such a service that is not cleaned up?
Taking your first email that would be
systemctl status check_mk@10-10.28.5.6:6556-10.28.5.1:42844.service
I'd be interested in the output of
find /sys/fs/cgroup/system.slice/system-check_mk.slice/ as well
As well as systemctl status system-check_mk.slice
