Hello, I'm seeing a lot of these messages in one of my proxies: aclMatchExternal: 'nt_group' queue overload. Using stale result. What does that mean? Previously I had problems with queue overloads but it used to deny access. Also this particular proxy seem to be a lot slower than the other ones (we currently operate several proxies balanced by a DNS round robin). Is there anything I can do to improve its performance and get rid of these warnings? The acl and auth helper is the following: auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 256 auth_param ntlm keep_alive on external_acl_type nt_group ttl=10 concurrency=5 children=20 %LOGIN /usr/lib64/squid/wbinfo_group.pl -- Diego Lima
