A little more information on the setup.

Yes, we are running Spamassasin and ClamAV on the same box.

First: Do not top post!

Well this is your problem. These processes are very CPU and memory intensive. Move these functions, an SMTP as well, to another system. Use a three tier approach.

We do have quite a few Shared folders.

These are also going to exacerbate the issue.

We have moved webmail to another box (Horde) this is not used very much.

Again, this isn't your biggest issue.

We have converted all of the db files to skiplist. (this was done so we could migrate from a G5 Xserve to Intel and for speed increase).

That was wise just from a stability standpoint.

If you are running low on RAM, you can tell this pretty easily by using top in the terminal. Just leave a terminal window open and run top in it. When you start having the massive slowdown, look at the pageouts. If it's increasing, that means you've run out of RAM and the OS is compensating by using disk. That will easily cause the symptoms you're seeing.

Pageout metrics alone aren't going to be telling enough. Especially since most of the pages you'd be dealing with wouldn't get paged out through the page files anyway.

You're probably right. I assumed some other things. I should have added that the free mem will be close to 0 and the pageout number will be increasing quickly.
