Re: [squid-users] Problem with increasing memory utilization

Hi!

I'll give a try, but something that deserve mention is that in my office I
have a linux server with squid 3.0 and this is not happening. Besides the
machine itself, the other difference is the mandriva version (here I have
2006.0 and in my clients I have 2008.0). I'm downloading the 2008.1
mandrinva version and will try with it too.

Thanks,
Leandro

Try squid-2.7; a bunch of delay pools related fixes went into there
which should be fix the reconfigure case?
