JT,
I think you might be right about email sending being the root of my
problem here.  I haven't seen one of these 500s since I put a stop to
form mail spam.  We'll see how it goes.  I'd like to switch to RPC
mode if that cleared it up for you, but I'm on 5.2 and there is a bug
that prevents op=tq from working with RPC mode.

I'll keep the list posted on how this goes.
