I recently installed three Pentium 166 boxes with 256 Mb RAM and 2 Gb HDD (SCSI via Adaptec 2940 PCI) and SMC EtherPower UTP card. Works fine and dandy, compiled a new kernel to support all of it. However: somehow this nice and dandy caching mechanism of FreeBSD gets me out of memory fairly quickly. I am running a little BSDI application (VideoOnDemand server), which loads files, sized about 5 Mb each, skips 4 frames after each stored (so the memory load should be 5 times as small as the file sizes). What I get is fairly simple to describe: first of all the program uses much more than the file-sizes divided by 5. I am not too worried about this problem. The problem I am really worried about is the fact that the OS caches all files that have been opened and does NOT release the memory when system memory is getting low. A solution would be turning the diskcaching off, but I wouldn't have a clue how to do that (and I am quite 'into the kernel' already !) ... Hopefully one of you experts have a solution. Your answer or suggestion is highly appreciated ... Regards, Taco Scargo WebGuide B.V. Amsterdam, The Netherlands e-mail: taco@webguide.net tel: +31 20 3116464 fax: +31 20 3116444
