Hi, a new issue. I have noticed that Squid stops and starts automatically. My /var/log/messages shows : . . . . squid[20957]: assertion failed: ACLProxyAuth.cc:227: "authenticateUserAuthenticated(checklist->auth_user_request)" squid[13183]: Squid Parent: child process 20957 exited due to signal 6 squid[13183]: Squid Parent: child process 15196 started squid[15196]: Starting Squid Cache version 3.0.STABLE13 for i686-suse-linux... . . . My Squid version is Squid Cache: Version 3.0.STABLE13 Any ideas ? Thanks! Augusto.-
