NetWare agent crash with ArcServe 2000

[chip301]

I'm running a Win2K Server with ArcServe 2000. This is backing up a NetWare 5.1/SP3 server. When I backup using the NetWare agent, NWAGENT on TCP/IP, the first time it works fine. But ArcServe 2000 can't talk to the agent on the second try. This always happen. The only way I can fix it is to unload all NLMs associated with NWAGENT and reload them. But that means unloading and reloading the nlms every time I need the agent for NDS backups.

Why would NWAGENT crash on the second time around?
Did anyone have this problem, and how was it fixed?

I have the same problem. The source is the new climb.nlm. For now, Novell and Cai hove no patch for.

I tried going back to the backed-up version of my pre-sp3 SMDR.NLM and TSA500.NLM, but they almost crashed my server.
It issued a critical error and then autospawned another command prompt. I had to restart the server. After the reboot, the abend log says the SMDR.NLM that was owned by SBSC.NLM was the offender. Needless to say, I switched back to the original SP3 nlm files. What does the climb.nlm do?
