Thank you for starting this.  I'll try to gather up information I've
been trying to collect here and post it in the next few days.  

RE: could be zombie related -

Where might I find more info on this?  Could this zombie issue be
present in FCGI as well?  

We have noticed once restarts start they get worse when under a load. 
I've been suspecting that the longer pages take to load the more people
are just stopping the page load, and this would/could create a zombie. 
The problem is I don't know how to identify or research what is going on
under the hood.  Could when someone terminates a connection be an issue
here?  I mean; if the request in queued waiting for a thread might act
differently than a request that is being processed by Zope and waiting
on a DB query, or even termination once zope has already started passing
results back through the pipe.  Our restarts are so hard to tie down I'm
guessing it's a very subtle issue or a combination of just the wrong
factors.  

Just some more food for thought.
