Re: Most stable non-mem-leaking squid?

Hello.
I had a problem with squid - when running for 2-3 days it got very slow. I
thought the reason was some memory leak - squid used to grow with 1-2 MB
for 20-25 hours. Upgrading from linux kernel 2.2.6 to 2.2.10 solved the
problem. The mem leak is still present though, but I prefer to wait for
stable 4, instead of patching with the memleak fixes.
