[squid-users] Squid CPU 100% infinite loop

Hello,

I have problems with squid 3.3.4. Every 30 minutes (with 300 users),
squid goes
to an infinite loop and freeze all web connections (99.9% CPU used)

Squid is installed under OpenBSD 5.2

Here are my compile options:

Squid Cache: Version 3.3.4 configure options: '--enable-pf-transparent'
'--enable-follow-x-forwarded-for' '--with-large-files' '--enable-ssl'
'--disable-ipv6' '--enable-esi' '--enable-kill-parent-hack'
'--disable-snmp' '--with-pthreads' '--enable-ltdl-convenience'
'--enable-auth-basic=none' '--enable-auth-digest=none'
'--enable-external-acl-helpers=none'

Here is the configuration:

authenticate_ttl 2 hour
authenticate_ip_ttl 1 hours
include /etc/squid/squid.acl.conf
include /etc/squid/squid.http_access.conf
http_port 3128
http_port 3129 intercept
