Hello, I am doing some performance testing on FC5 with squid 2.6-S2 I am getting the following error when I use cache_mem 4 GB FATAL: xcalloc: Unable to allocate 1 blocks of 4112 bytes! Squid Cache (Version 2.6.STABLE2): Terminated abnormally. And it restarts after that, thereby completely killing the test. I have 16GB of memory. Is there a better way to ask squid to use as much memory as possible, since I have ample of it.
