I am hoping someone can help me locate the cause of the problem I am
facing with NSD 3.0.7 and Solaris 9. There are certain warning
messages in syslog and nsd-patch coredumps due to SIGBUS. However if
the number of zones is around 4 it works fine. I tried increasing
resource limits in solaris but however prstat will always show 10M
Size for NSD
I have posted some debugging output below:
Thanks
