Environment
Novell NetWare 6.5 Support Pack 5
Novell eDirectory 8.7.3.7 for NetWare 6.5
Situation
Server appears to be abending in many different NLMs.
NetWare server abending after applying NetWare Support Pack 5
Abending in DS Running Process: Health Monitor Slow Process
Thread owned by NLM: PORTAL.NLM
Current EIP is DS.NLM|FreeSearchIter
Resolution
The reason the server appears to be abending in multiple NLM is because the error is a double free. This means a process is attempting to free memory that has already been freed. This in turn means two processes prior to the abend were allowed to use the same memory location which can result in that region of memory being corrupted. To identify specifically where the abend is occurring the " set alloc memory check flag=on " parameter needs to be typed at the console of the server.
(NOTE: This parameter may make the server abend more frequently so should only be used for troubleshooting purposes.)
If the abend appears to be in the Health Monitor Process please apply eDirectory 8.7.3 Support Pack 8 or greater.
