Hello again, We have found an issue in backend.conf, as the Rock cache_dir is SMP aware. Change this... #cache_dir rock /cache${process_number} 2097152 to this... cache_dir rock /cache1 2097152 ... then the new errors are: Nov 23 14:55:28 px06 squid[12559]: ERROR: /cache1/rock communication channel establishment timeout Nov 23 14:55:28 px06 squid[12559]: FATAL: Rock cache_dir at /cache1/rock failed to open db file: (0) No error. We have search for in the forum (http://squid-web-proxy-cache.1019090.n4.nabble.com/RockStore-quot-Fatal-Error-quot-td4666691.html), and tried what other people suggested without success. /cache1 drwxr-xr-x 2 squid squid 16384 nov 21 13:05 lost+found drwxr-xr-x 2 squid squid 4096 nov 23 12:38 rock The permissions in /dev/shm are correct, too.
