I am having a serious problem with my site running out of memory.  apache is 
leaking memory/processes.

I have half a dozen virtual hosts, but relatively light traffic, around 40,000 
accesses per day (that includes all files on all hosts), so on the order of 1 
access per second average.

Currently my 512MB slicehost slice (1GB swap) starts off at about 100MB used, 
and then grows over a few days to fill RAM and start using swap, at which point 
I restart apache and the process repeats.

However I have a release coming up, and that will increase the traffic 
substantially for a short period of time, and its imperative that the site 
doesn't go down.

Most of my pages are plain pages, but some of them are mod_perl perl pages.

I disabled most modules, remaining are only:  authz_host   dir   headers   mime 
  negotiation   rewrite   status   env   perl

More server stats are below if they are useful.

The problem appears to be that the worker processes get caught in a read and 
never finish and never die.

/usr/sbin/apache2 -f /etc/apache2/apache2.conf -k start

If I can't find an answer, I'm going to have to do something desperate, like 
switch to nginx, which entails rewriting all my mod_perl pages at fastcgi 
pages, which will take a lot of effort.

What am I missing?

Lots of server stats follow.

Thanks,
   Peter.
