[squid-users] winbindd: Exceeding 200 client connections, no idle connection found

Hello,

Since a few days ago I can't grant acces to users on my company network
using Squid.
I am having problems with 2 winbind processes that are using a huge
amount of CPU when users enter the system.
The following is the winbind log:
> nsswitch/winbindd.c:process_loop(813)
> winbindd: Exceeding 200 client connections, no idle connection found

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
