Environment
Novell-bind 9.3.3-122.134
Domain Services for Windows
DSfW
Multi-core processors (2 or more cpus)
Situation
namecd, novell-xredg, and micasad are all running and working properly. When novell-named is restarted, dns starts with out having to restart any other service.
named.run log shows the following:
02-Feb-2012 10:05:15.934 general: server: info: Failed in getting question name : Checking for StartStop / Dynamic update query

Resolution
The workaround is to load novell-named in single threaded mode
/opt/novell/named/bin/novell-named -u named -n 1
A new binary that addresses this issue can be obtained through Novell Support. Reference this TID until the next Maintenance patch is released with the new binary.
Additional Information
Multi-thread server increases effective utilization of the CPU in the multi-core processor and it is designed to not impact query response during dynamic reconfiguration time.
