Core was generated by `/sbin/cgmanager -m name=systemd'.
Program terminated with signal SIGABRT, Aborted.

How often does this happen? Can you trigger it in a particular way?
Are you able to do
cgm listcontrollers
cgm getvalue memory . memory.limit_in_bytes
cgm listchildren memory .
cgm create memory x1
without any crashes?
