- HP 9000/847, running HPUX 8.02.
-
- From time to time, I see processes that get into such a state in
- which they cannot be killed. By 'cannot', I mean that kill -9
- as root does not work. I had formerly been under the impression
- that root kill -9 meant absolute instantaneous death, but apparently
- this is not the case (or there are some serious bugs).
-
- One case is when a process crashes and is attempting to write
- out a large core file across the network (eg. to a remote-mounted
- NFS partition). Under the coredump is finished, the process won't
- die. Another case appears to have something to do with sockets;
- the process won't die while it thinks it has active remote
- connections.
-
- If these situations are not indicative of an OS bug, has anyone
- built up a list of conditions in which a process cannot be killed?
-
- Any assistance is greatly appreciated,
- - Jason (jmay@ctp.com)
