Recycle 100% .net web app pool

Hi,

Is there still any reason to recycle 100% .net web apps?

At the time when our website was a hybrid of VB/COM/C++ we
needed to
recycle the pool, to get rid off memory fragmentation, but
with .net,
this should not be needed, is it?

The real reason I ask, is that we have a high traffic site,
with
several webservers.
Now, when one is starting to recycle, it is noticeable. And
due to our
installation scripts, the servers will recycle almost all
together...
ouch!

I was looking for a way to, maybe, schedule the recycles,
but then I
thought, why do we still recycle the pools?

I ran a production server with recycling disabled for weeks
on end.  I did
some in-memory logging (dictionary) and that was causing
high memory usage
when things were going wrong, but the advantage was that I
could run
"services" inside asp.net and some of those
services would run on a schedule
(like a cron job) and clean up the in-memory logging by
filtering out needed
information to database and removing the rest from memory
(like debugging
info).  Even though it had a fair amount of traffic I
wouldn't have
considered it a high traffic site.  It did, however, do an
awful lot of
processing 24/7 (I moved windows services into the asp.net
domain for web
administration).  There was no unsafe or unmanaged code.

Regards,
Brian
