Hello everyone In one of my clients squid frozen. Looking at cache.log I saw the last line w/ an error message: Tunnel State Data Connection error FD 265 read/write= failure (32) Broken pipe It is not the first time that it happens, but this time I could see this message before restarting squid. It is a bug or a normal message indicating a sporadic error?? Using:3.1.6-1.2+squeeze2 + debian squeeze + kernel 2.6.32-5-amd64 best regards
