[squid-users] ERR_CONNECT_FAIL 110

[Alfredo Rezinovsky]

I have a few TPROXY implementations with squid. In only one of them 
recently I'm getting lots of: "x-squid-error: ERR_CONNECT_FAIL 110" and 
some 504 timeouts.

Squid Cache: Version 3.4.10-20141218-r13197

Is a custom compiled squid with everything I don't need disabled.

Running in Ubuntu with kernel 3.13.0

PMTU from the proxy to both the servers and the clients seems to be 1500.

Any clue?
