GWIA causing high CPU usage

Today our GroupWise 6.5 server was so slow and causing lots of errors in the mail client.  I checked the server and found the CPU was at 100%.  It would not go down.  I then stopped the GWIA service and the CPU usage went back to normal.  I found about 20 files in the GWWork folder and as soon as I removed them the CPU usage went back to normal.  

What caused this?  Is there a tool to look at the files in this folder and see what they were?  

I know I am explaining this crudely but I hope you understand.

Yes, that's enuf of a problem description. Exactly what version of GroupWise v6.5? There's been like 5 Support Packs for it.

Also, what platform? GroupWise v6.5 can run on Linux, NetWare, Solaris and Windoze. Which one are you using?

We are running GW 6.5.0 on a windows server 2000 sp4.

OK, the latest is GroupWise v6.5.5. I would suggest applying the latest Support Pack as the first troubleshooting step.

I have seen, over the years, where badly malformed MIME, or corrupted message headers, can cause GWIA headaches. This sort of problem is usually associated with E-Mail sent from "broken" systems that don't comply with standards, or with SPAM.

As much as I like GroupWise, I have to say that GWIA is probably the weakest/least-robust component. I usually front-end my GroupWise systems with a MIMEDefang/sendmail combination that gives me much better anti-SPAM (than *any* of the "big 3" E-Mail systems) and also allows me to rebuild inbound E-Mail and ensure it conforms to standards. I'd do the same for Exchange or Notes.

I really wish they'd introduce GWIA's SMTP functionality as a sendmail MAILER module, or at least allow the "Third" directory function to reference a UNIX-style or network socket.

psicorp, thanks for the detailed message.  I will try the patches and see what happens.  I have never patached a GW system on a Windows 2000 server.  Have you?  anything to look out for?

Sorry 'bout that.

I avoid W2K like the plague upon mankind that it is, so, no, I'm afraid I can't offer you any info. The documentation in the Support Pack should have info on the installation steps.
