I'm using the 2 leak patches posted at the nlanr site a weekend or two
ago, plus SRB's leak patch, and 2.2.S3 still can't run more than a day or
two. I have a client running squid-1.1.22. His squid process has been
running since mid April with no visible memory leaks. His is a _much_
smaller, lighter used cache doing transparent caching, but no ICP. I'm
probably going to just downgrade next week and see if squid-1.1.22 is as
stable under heavy load.
