Hi Squid 3.3.8, 64Bit Linux: I have the following helper configured: ... external_acl_type SQUID_KERB_LDAP ttl=7200 children-max=50 children-startup=20 children-idle=5 negative_ttl=7200 %LOGIN /usr/local/squid/libexec/ext_kerberos_ldap_group_acl -g "XXX" ... When I startup squid from scratch, then I got 20 (children-startup) helper processes (as expected). When I rotate squid logs (squid -k rotate) afterwards, then it startups just 5 helpers (independent of any value in the external_acl_type-directive). Look here: $ /etc/init.d/squid start squid 8992 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 8993 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 8994 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 8995 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 8996 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 8997 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 8998 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 8999 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9000 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9001 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9002 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9003 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9004 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9005 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9006 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9007 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9008 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9009 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9010 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9011 8981 0 07:17 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX $ squid -k rotate squid 9767 8981 0 07:19 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9768 8981 0 07:19 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9769 8981 0 07:19 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9770 8981 0 07:19 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX squid 9771 8981 0 07:19 ? 00:00:00 (ext_kerberos_ldap_group_acl) -g XXX Probably a bug? Thank you. Kind regards, Tom
