> cache_mem 4048 MB This is not the size of the cache in total, it is only the size of the cache in memory. Do you have enough memory to allow for 4048 MB cache mem, and the mem for the OS, and the mem for the squid process and the mem for the index of the cache files on disk?
I have not seen any cache_dir lines in your config, so i assume you use the default of 100 MB. Normaly you should use a big disk cache size (cache_dir) and a small mem cache size (cache_mem) not bigger than 8 MB. Hermann
