Recently, I noticed that my HP9000 320 machine was running quite
slowly. Although I do not know for certain what the cause was (a
reboot cured all - 'til next time 8-)), I noticed that there were
8 cu sessions show "ps -ef" output. These processes were executed
by folks not currently logged onto the system. They had "valid"
PIDs but the PPIDs were 1 in all cases. Okay, so what probably
happened was that whomever was using cu at the time logged out
without going through the ~. sequence. But, in attempting to
discover if this could be my problem, I further discovered that
I could not kill these processes. Of course, I tried "kill -9 pid"
(as root) but the processes would not blow away. So, I tried
sending a SIGCLD (kill -18 1) signal to init to see if it would
terminate the rogue cu processes. No luck. So, I am a little
confused. I thought that root could kill ANY processes (including
init and swapper) but this appears to not be correct. I have a
gut feeling that the zombie processes owned by root has something
to do with this problem. But I am not sure
Any who, any ideas?
