Hello David, I'm not familiar with freeIPA, but anyway you can start by better identifying the process. In top, get the PID and look under /proc/$PID - in particular exe will be a link to the binary, like lrwxrwxrwx 1 root root 0 Nov 27 01:41 /proc/1/exe -> /sbin/init
pstree -p -H $PID will help you identify the parent process, if there's one.
