We were just stress testing a forward proxy of ours, and suddenly received this error which made squid crash pretty hard, apparently. 2014/05/22 11:38:13 kid1| assertion failed: client_side.cc:1515: "connIsUsable(http->getConn())" 2014/05/22 11:38:18 kid1| Set Current Directory to /var/spool/squid 2014/05/22 11:38:18 kid1| Starting Squid Cache version 3.4.4 for x86_64-redhat-linux-gnu… I couldn’t turn up anything by Googling. Anyone have any idea what went wrong? Dan
