On a Netware 5.0 box with dual 450MHZ processors, 512 megs ram, Intel 440BX motherboard...RAID 5 on and Adaptec controller.We have run fine for a couple of years on this box and then about 1 month ago the server CPU utilization climbs to 38% and then suspends all the proceses and server.nlm ( all NLM`s ) get suspended. Have tried swapping RAM, new cables to hard drives on array. Nothing in any of the logs ( abend,syslog,volerr,tts , etc. ) so it`s really hard to pinpoint. Anybody out there seenthis or have any tricks to troubleshoot the problem. Thanks in advance

How about disabling or removing one of the CPUs? I think if you remove a cpu you have to put a "dummy card" in the processor slot.

Try running on a single CPU. If that works, put the removed CPU in place of the functioning one to see if the processor has a problem.

Have you applied any recent service packs that might impact the server? (just a thought)

Good Luck!

Ok..I took the second CPU offline last weeek right after I posted this question and it`s runnin fine.But it still makes me wonder " what changed ". No I haven`t put any new SP`s on the box. For some reason everytime I put a service pack on this system I loose the ARRAY controller. Novell and Adaptec don`t know why either. Thanks for your help and response.

I agree with the other poster. Netware won't really use the second processor for very much, so just get rid of it. Netware on 1 processor is faster than NT on 4 anyways. Chances are the users will never see the difference, as your Hard Drive transfer rates will be the limiting factor for the server anyway.

Anytime a computer just randomly locks up and crashes, it suggests a heat problem. Make sure that all the fans, power supply fans, cpu fans are working. Next, comment out all but the basic packages in the autoexec.ncf file and see if it keeps working. Then, one by one start the packages and see if it works or not. Check to make sure that the SYS volume has enough space. Use monitor > Kernel > Threads to see the hardest working NLM/s to see which ones are really giving the processor a run for its money. If you have a Dell or Compaq server, make sure you are running the right PSM (platform support module) from the manufacturer for dual processors.
