[squid-users] FATAL: cache_swap is lower than cache_mem

I have a squid 2.4S1 machine running on RedHat 7.1 that has 1GB of mem(soon to be 2GB) and would like to be able to use all of it. Except that when i set the cache_mem option in squid.conf to anything higher than 64 MB I get the following error: FATAL: cache_swap is lower than cache_mem. I do not see a cache_swap in the squid.conf, is there something I am missing?
