We have been having problems--our users have been reporting 500 and 503
errors which do not appear to be correlated with much of anything.  Our 
hosting site was having DNS problems which now appear to have been
resolved--more machines, caching servers split from authortative servers,
and so forth.

Initially we were having a problem:[...]

mark.fontana(at)efi.com provided a patch against Pound 1.4 
[...]

which solved our immediate problem.  We've been running Pound 1.4
successfully for a while.  Our current configuration sets

	Alive 	30
	Client	 2
	Server	 0

Users have continued to report 500 and 503 errors although we believe that 
the DNS upgrade will eliminate most.

So, I am now pondering moving to the latest version of pound (abandoning
Fontana's patch) and changing the settings for Client.  We orignally
reduced Client from 10 to 2 because many of our users use IE on XP and
there is said to be a perfomrance problem with longer settings.

1) Are the default settings still the recommmeded ones?

2) We have nearly 400 UrlGroups as we use Pound as a reverse proxy.  Is
this a potential performance bottleneck?  If so, any thoughts as to how 
to configure things for better response?

3) We see occasional errors in the logs.  Some are to be expected, some
are indictions of errors elsewhere in the net.  Any words of wisdom as to
how to sort out the latter from the former?

4)  What's the current recommendation for a production system?  Should I
snarf Pound-current or another version?

Thanks.
