Hi, I have 10 SCSI Hard disks each 73GB and 8GB of RAM I configured squid to use 28 GB on each cache_mem 512 MB cache_dir aufs /cache1/ 28000 32 256 cache_dir aufs /cache2/ 28000 32 256 cache_dir aufs /cache3/ 28000 32 256 cache_dir aufs /cache4/ 28000 32 256 cache_dir aufs /cache5/ 28000 32 256 cache_dir aufs /cache6/ 28000 32 256 cache_dir aufs /cache7/ 28000 32 256 cache_dir aufs /cache8/ 28000 32 256 cache_dir aufs /cache9/ 28000 32 256 cache_dir aufs /cache10/ 28000 32 256 after running squid for a while top command gives the folowing Mem: 8315908k total, 4488024k used, 3827884k free, 720496k buffers Swap: 15631236k total, 0k used, 15631236k free, 1160248k cached PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND 17962 squid 18 0 2836m 2.3g 3664 R 97.6 28.9 4035:06 squid When I increase ecach cache dir size squid process takes more memory and cpu becomes more busy, this leads to a full system crash (not immediatelly but after a while more than 5 days), I could not figure out the real source of this crash bu it is a kernel panic and the squid process ID is mentioned in the error messages on screen Can I take advantage of the remaining disk space on each Hard Disk? Do I need more RAM? Or squid just can not handle this big amount of Resoures (HD and RAM)?
