HIGH CPU UTILIZATION

[jahill98]

After install nw6sp3 and nw6nss3a, server has been experiencing 100% cpu utilization. Especially when running the McAfee Netshield (anti-virus) program.

Server: Compaq Proliant - 866/133 mhz - 1 g Ram

Anyone else experiencing this? - I re-applied the support pack 3 - no difference.

Thanks,

I would take out all the services you are loading in your Autoexec.ncf file and load them manually one at a time. BY doing this you should be able to monitor what service is causeing the CPU drag down. Most likeley this service needs to be upgrade to be more compatible with SP3.

Good Luck

There are known issues with McAfee on NetWare 6 that aren't documented very well.. They have a patch that fixes the initial compatibilty problems anyway. You should be running version 4.60a (not 4.60). You should be able to get it from McAfee but you have to prove that you bought it, they don't just let anybody download it.

Whether this will fix your issue, i don't know. But I'd say it's a good place to start. The problems I've seen with it are odd, but related to NSS and McAfee. A network had NW6, SP2, and McAfee NetShield. Every time the admin tried to add space to his NSS volumes, the server would abend. Abend.LOG showed McAfee as the cause. Very wierd, but once we applied the mcafee patch, no futher problems have occurred.

Also with Compaq servers, make sure you've also put on the latest Proliant Support Pack. As of today, it's PSP v6.40.

Hope that helps.

A question,

Would Mcaffe on a local machine also cause this to happen as well?? Instead of on the server. Where it goes out and tries to scan the network drives?? Just curious. The thought hit me as I was reading this that there are a few in my district that have McAffe installed and running.

Think it is a possibility or am I blowing smoke???

Well, as a rule, I would let the server itself handle any scans on its own file system. No reason to have the users scanning it. Workstations should only be configured to scan themselves.

If you think about it, if they are scanning network drives, it has to do a directory search, open each file, read it, process it, and close it. Do this over and over and I could imagine that it could contribute to high utilization. Plus it will create extra network traffic.

Whether this is the cause, I don't really know, but you could probably set up the scenario and test for yourself.

I found out that the Nss patch was a beta patch when applied and had issues - After filing an incident report with Novell, they sent me the corrected nss patch and now everything is running normal.

Thanks for all the help.
