I have had a Squid server that has been running for some time, and all of the sudden started having problems, this server runs as both a forward and reverse proxy on different ports. The reverse proxy part seems to be responding fine, but the forwarding is all of the sudden logging errors in cache.log file about tunnelSate The parent server appears to be running fine, and is serving requests for a few hundred clients that access it directly without issue. Of course the full log message is exactly what the subject of this email message is. tunnelConnectTimeout(): tunnelState->servers is NULL The parent server is running 3.1.20 and this server is on 3.1.18, anyone have any idea what would cause this type of behavior to start happening?
