A defunct process (aka zombie) is a process that has terminated either because 
it has been killed by a signal or because it has called exit() and whose 
parent process has not yet received notification of its termination.  A 
zombie process exists only as a process table entry and consumes no system 
resources. This entry is retained to hold the child's exit status until the 
parent process wants to retrieve it. The parent can also be notified 
asynchronously via a signal of the child's termination.  We always seem to 
have one defunct process associated with processz3950que and our z3950 
searches work just fine, so you probably need to look elsewhere.

How are you restarting the daemon?  When I need to do this I do
ps -ef | grep z3950 
kill -9 <pid> <pid> ... 
/usr/local/koha/intranet/scripts/z3950daemon/z3950-daemon-launch.sh

Have you made a change to the z3950 config within koha?  Can you ping the 
z3950 servers?
