Hi, We are using squid for caching, with SCSI disk and 512 MB RAM. The cache_mem setting in squid.conf is 64 MB. After running for several hours total free RAM (as seen by top command) reduces to few kilobytes and server response time increases (CPU idle cycles also go to zero), and we need to reboot the server. Though as percentage of total CPU usage squid is usually taking around 15-30%CPU and percentage of RAM as 12-15%MEM . After rebooting the server would again run fine for several hours say half a day, and then RAM would gradually get consumed again. Any suggestions are welcome.

"Hidden node" problem can be avoided by the use of RTS-CTS (request to send, clear to send). RTS-CTS are optional but can be enabled. You can also specify a threshold in the size of the packet under which RTS-CTS will not be used, in which case the hidden node problem might occur for those packets. RTS-CTS will solve the hidden node problem, but will consume BW.
