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

--enable-ltdl-convenience
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?
