Hi all, using squid 3.0stable18 I got this: 2009/09/21 13:37:32| externalAclLookup: 'plUser' queue overload (ch=0x18c3b78) FATAL: Received Segment Violation...dying. plUser is an external ACL witht his definition. external_acl_type plUser children=64 ttl=900 %SRC %LOGIN /etc/squid/ip-user- helper.pl -H 127.0.0.1 -M red -T 900 -D cn=Manager,o=XXX -B o=SAT -w "XXXX" acl plU external plUser I'm pretty sure this acl works, it has been working since october 2008, how ever load on server is higher. I wonder if I got a new bug. TIA LD
