Thanks everyone for your replies.  Turns out that this error had nothing
to do with the problem I am trying to track down.  I will post a new
thread with a more appropriate subject line.

The error is presumably because your fast cgi system has a timeout. Do
you have some code that sometimes  takes a long time to run? If it only
happens about 1% of the time it may be normally just quicker than the
limit, but occasionally going over.

For what its worth, I also get the latter error quite a bit in my
error logs.  Haven't really had time to trace it down, looks similar
something like:

 [Tue May 06 10:09:34 2008] [error] [client] FastCGI:

incomplete headers (0 bytes) received from server


I think the only thing in common here is Session::State::Cookie;  we
use Session::Store::Cache.   Probably doesn't help much but I guess
the problem does exist for various reasons if anyone has any ideas I'd
be glad to try, but "adding some debug messages in key places" isn't
going to cut it.
