We often get "runaway" procs that eat CPU. Normally these are instances of the survey software we use and I just kill them.
However we have a process called "onlinet" using 25% CPU (which seems to be the max for a single process.)
It indeed has no parent process (PPID is 1).
I have no idea what it is for, so I am a little scared to kill it.
Esspecially because we have NO software support on this machine. IBM stopped supporting AIX 5.1 at all in April. So we have hardware support only.
Can anyone (perhaps my favorite AIX guru; wmp) give any insight? ;)
