Hello, squid crashes after following error assertion failed: DestinationIp.cc:41: "checklist->conn() && checklist->conn()->clientConnection != NULL" >From the error massage i guess that following config may cause the problem #acl download_until_end_by_ip dst 13.107.4.50 acl freetimes time 03:00-08:00 #range_offset_limit none download_until_end_by_ip freetimes As you can see i have commented first and third lines to see what happens . Still soon to be sure but after commenting those lines the problem did not happen . Maybe a bug !
