user processes make system calls and enter in kernel mode.

if this calll hangs you won't be able to kill -9.

you might even have to reboot your box to get it free,
but you should find out what the precess is supposed to do and why it might hang

good luck

Hi

As per my experience rebooting is the solution for this problem. Before that U can try killing all process which are initiated by that particular user.

Hi,
some of the user processes use the IPC's to make system call(s) to kernel, if such processes hangs kill can't kill such processes, rebooting the m/c is only the solution

Hi

If this process is a zambie process, you are not able to kill it ( this kind of users process are coming from bad programming ).
Zambies process appears when a forked ( child ) process executes an EXIT instruction but his Parent process do not wait for him during his time life ( wait instruction ) even . Then , the forked process becomes a ZOBIE .
