Rails - Mar 2006 - Lighty+Mongrel unresponsive after so many requests

I transferred a site from Lighty+SCGI to Lighty+Mongrel, and now I''m 
having problems with it becoming unresponsive. It works fine for about 
10-15 minutes, but then attempts to access the site just stall forever. 
Nothing is written in any of lighty''s or mongrel''s logs.
Here''s my
lighty config:

$HTTP["host"] =~ "www.xyz.com" {
  proxy.balance = "fair"
  proxy.server  = ( "/" => (
    ("host" => "127.0.0.1", "port" => 8010),
    ("host" => "127.0.0.1", "port" => 8011),
    ("host" => "127.0.0.1", "port" => 8012),
    ("host" => "127.0.0.1", "port" => 8013),
    ("host" => "127.0.0.1", "port" => 8014),
  ) )
}

And I start the mongrels with:

mongrel_rails start -n 5 -d -e production -P log/mongrel-10.pid -p 8010
...

Any idea what the problem is? I just updated mongrel to the latest 
version, but that didn''t fix the problem. It''s just this site
that''s
having the problem too - others continue to work fine while this one''s 
unresponsive. But this site also gets a lot more traffic, so that may 
have something to do with it (but the server has plenty of free RAM and 
CPU). I tried switching the proxy balance to "hash", which worked
about
the same (and became unresponsive after about 10-15 mins); and 
"round-robin" didn''t work long at all before displaying 5xx
errors.

Well, I switched from Mongrel to SCGI on this site about an hour ago and 
it''s still running fine, so I guess the problem was Mongrel :(.

One thing I noticed on my other sites running Mongrel, which get far 
less traffic, is that after a lot of requests they''d get slower and 
slower - taking about 1-3 seconds to load, as opposed to instantaneous. 
Restarting Mongrel restored performance.

Thanks Joe,

I''ll be taking a look at that, but if you can grab me off line so I can
chat
with you about the server.  I sent you an offline e-mail with my info.

P.S. Just in case it''s not obvious, I wrote Mongrel (with some help).
