Thanks! I've added the children-startup=15 to my config but it seems to be ignoring it. An excerpt of my config is: external_acl_type internet_domain_group children-startup=15 %LOGIN /usr/lib/squid3/ext_ldap_group_acl -R -P -b (this then goes on to provide details of AD structure etc). Have I missed something? -- View this message in context: http://squid-web-proxy-cache.1019090.n4.nabble.com/Increase-number-of-ext-ldap-group-acl-processes-tp4670484p4670488.html Sent from the Squid - Users mailing list archive at Nabble.com. _______________________________________________ squid-users mailing list squid-users@xxxxxxxxxxxxxxxxxxxxx http://lists.squid-cache.org/listinfo/squid-users
