We deployed support pack 6 on our NetWare 6.5 servers and now after
sometime, less than a day, DNS stops working. The nslookup screen says
"QUERY FAILED DNS request timed out." We have tried unloading named.nlm,
netdb.nlm, netdb.mpm, gwpoa.nlm and ndpsgw.nlm. Then reloading them, this
did not fix the problem. So far the only solution is to reboot the servers.
