Hi Malcolm,
do you have a simple test case for this? I've tried with running several
nsadmin against nsd but was not able to cause a crash. Also why have you
disabled threading? Any particular reason for it? It would also be good
if you tell us more about your platform (ie. OS version/compiler
version, service packs/patches etc.)
Cheers,
Karel
