We have a fairly busy web service, we do notice steady reports of e500 errors. 
 They might relate to some trouble reports we get occasionally.  Is there any 
advice on how to trouble-shoot this further?  Is there any chance pound will 
think the web server is dead and deny requests for a few seconds until it sees 
requests are processing there?

Thank you.

I think that's Chrome. I see the same thing.

I brought it up on another list, and the reasoning seems sound.

It's annoying, but harmless. If it really bothers you try increasing the
client time-out.

Thanks Simon and Robert for the feedback (suspicion about Chrome and that it's 
not fatal).

I'm a bit confused though, if a client makes a specific request (e.g. save
data) 
and it fails why would that just be annoying?  I assume if Chrome is warming up

connections would not call a specific URI.  Is this timeout waiting for the 
client to respond, or?

Steve
