Thanks Khalid,

Its on every page so its not something specific I could narrow down in
Drupal other than the autoload that's including field.module for
things like FieldException on every page. But that shouldn't really
matter.

That's interesting that you didn't have any problem. I was using
gentoo's mod_fastcgi with hand compiled versions of php 5.2. I'll try
fcgid and maybe a couple of versions of php if that doesn't make a
difference.

I don't think fcgid vs. mod_fastgci would make a difference.
The hand compiled version of php may have something to do with it.
I use the standard one provided in Ubuntu's repository (LTS version).

Seeing if another opcode cache like APC would trigger it
would be interesting too.

APC works fine for me. In general I have seen that Xcache would crash
while APC is mostly stable. Every time I try experimenting with anything
other than APC, I go back to it. It is developed by many of the core PHP
folk too. But all that has to be qualified with specific version, environment,
...etc. YMMV.
