I have a Netware 6.5sp5 server that has been running forever without any problems. Suddenly today it had multiple abends that caused a system restart. Upon restart the first message that appeared said "Multiple Abends on Processor 0 System Halted" followed by a screenful of 43 abends. The first few abends are:
30A7CA3EXENGNUL.NLM:XENGNUL.NLM (Data End) +140B1DE
B862BDEENWSA.NSS:ZH_LDOSOpen+4E
0029327CSERVER.NLM:EVENTREPORT+B0
002FDCF3SERVER.NLM:OutputProbableCauseMe

After approximately 30 seconds the server automatically reboots itself and runs through the entire scenario again. This is our only server. It runs DNS, DHCP, and file services. Everything is down at the moment.
