Hello, I'm seeing the dreaded "All ntlmauthenticator processes are busy" error 2-3 times a week which I can fix by restarting squid but the proxy only stays up for a few days at a time. This is our very simple squid.conf file acl snmppublic snmp_community test #Recommended minimum configuration: acl all src 0.0.0.0/0.0.0.0 acl manager proto cache_object acl localhost src 127.0.0.1/255.255.255.255 acl to_localhost dst 127.0.0.0/8 acl SSL_ports port 443 acl Safe_ports port 80 # http acl Safe_ports port 21 # ftp acl Safe_ports port 443 # https acl Safe_ports port 70 # gopher acl Safe_ports port 210 # wais acl Safe_ports port 1025-65535 # unregistered ports acl Safe_ports port 280 # http-mgmt acl Safe_ports port 488 # gss-http acl Safe_ports port 591 # filemaker acl Safe_ports port 777 # multiling http acl CONNECT method CONNECT http_port 192.168.3.100:80 http_port 192.168.3.100:3128 #We recommend you to use at least the following line. hierarchy_stoplist cgi-bin ? access_log /var/log/squid/access.log squid # redirector_bypass off url_rewrite_program /usr/local/squidGuard/bin/squidGuard -c /usr/local/squidGuard/squidGuard.conf acl QUERY urlpath_regex cgi-bin \? cache deny QUERY #Suggested default: refresh_pattern ^ftp: 1440 20% 10080 refresh_pattern ^gopher: 1440 0% 1440 refresh_pattern . 0 20% 4320 acl apache rep_header Server ^Apache broken_vary_encoding allow apache visible_hostname proxy.test.com snmp_port 3401 auth_param ntlm program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-ntlmssp auth_param ntlm children 15 auth_param basic program /usr/bin/ntlm_auth --helper-protocol=squid-2.5-basic auth_param basic children 15 auth_param basic realm Squid proxy-caching web server auth_param basic credentialsttl 3 hours acl NTLMUsers proxy_auth REQUIRED http_access allow all NTLMUsers Any suggestions to tune this to reduce the NTLM authentication error?
