Neither of us were entirely right. A zombie is a child which exited for
any reason but whose parent hasn't (yet) read its exit status. A zombie
should have released all resources apart from the process control block,
which is retained until its parent has read the termination status.

If the parent exits without reading the zombie's termination status it
gets inherited by init, which reads the status and so gets rid of the
zombie.

IOW, all child processes become zombies, but normally for a very short
period: for a zombie to persist for any length of time implies that its
parent has hung. Probably its either waiting for an event that will
never happen or is stuck in a loop that isn't checking for its children
to terminate.

Nope. It will only kill named processes but its a system-wide kill
unless you use the -u option to limit its effect to a specific user.
I've used it many times undel Linux and haven't yet had it kill anything
I haven't wanted it to kill.
 
BUT, in any case the OP's problem isn't in the zombie processes. Rather,
its in the process that spawned them. Run the command:

	ps -fu xxxx

where 'xxxx' is the name of your user. Find a zombie in the list and
look at the third (PPID) column, which identifies the parent process.
Find that in the second column and that's the process that is causing
the problem.
