Might want ps axf output. If they are console backends, something is not
right because perl shouldn't be long-lived (it should nowadays be either
sleep or ipmitool or ssh depending, with perl being their for only a few
milliseconds before not being perl anymore)).
If it is xcatd, the memory usage in top is misleading, but you still
shouldn't have a lot of xcatd all at once normally.
top -b -n 1 might also be interesting.
