Please also use a more recent squid release.
Currently supported releases are:
2.6stable17+ if you are running high-performance servers
3.0-stable1+ if you can.

Squid Cache (Version 2.5.STABLE14): Terminated abnormally.
I have been looking for some info and I've found this reopened
bug:https://bugzilla.samba.org/show_bug.cgi?id=3204).
Has anyone had the same problem and has succeeded on solving it?
It's weird because Squid was working great until I updated Samba from
Ubuntu repositories.
This is my Scenario:
S.O. Ubuntu 7.04
Versiones Samba y Winbind 3.0.24
Usuarios, sobre unos 500
Squid:
$ squid -v
Squid Cache: Version 2.5.STABLE14
configure options: --prefix=/usr --exec_prefix=/usr
--bindir=/usr/sbin --sbindir=/usr/sbin --libexecdir=/usr/lib/squid
