Hi, I have upgraded debian sarge and after that squid doesn't start. I have recompiled and reinstalled squid and I also reinstalled with the debian packages, but the problem still remain. Look the strace log: linux-ambiente:~/squid-2.5.STABLE7# strace squid execve("/usr/sbin/squid", ["squid"], [/* 16 vars */]) = 0 uname({sys="Linux", node="linux-ambiente", ...}) = 0 brk(0) = 0x8241000
