Hi, We were trying to configure the new RockStore as a replacement to the COSS from Squid 2.7. We are seeing these lines in "cache.log" FATAL: Rock cache_dir at /cachestore/cache1/rock/rock failed to open db file: (11) Resource temporarily unavailable Full cache.log is here: http://pastebin.com/dWD2di48 We have 4 RockStore cache_dir lines like the one below: cache_dir rock /cachestore/cache1/rock 20480 max-size=32767 swap-timeout=300 max-swap-rate=300 Full squid.conf is here: http://pastebin.com/cQEWZTuf We did a full umount, mkfs.ext4, mount & did a "-z" to recreate the cache_dir. That "-z" did not take any time at all, hardly 2-3 seconds. If I disable the 1st RockStore config line, then the 2nd gives the same error, so and so forth. Can someone help? Regards HASSAN
