Hello, It seems as if I am having problems with memory on my linux system at home. I am running Red Hat Linux release 4.2 and Kernel 2.0.30. XOSView and the free command report the same observation. When I run Netscape V3.2 with or without any cache setting and quit the application, the reported amount of free memory does not return to where it was before the application was started. When I do a hard boot and run "free" as the first command, I have about 40 Megs free. After running Netscape for about a week (start and stopped about 20 times) free reports: total used free shared buffers cached Mem: 63168 49800 13368 15000 18660 17744 -/+ buffers: 13396 49772 Swap: 16588 0 16588 As you can see, I have 64megs(edo) and a 16meg swap area. Here's what's running currently: bin 167 0.0 0.4 836 312 ? S Dec 31 0:00 portmap dave 19067 0.0 1.7 2416 1092 ? S Jan 1 0:00 fvwm95-2 -f FvwmM4 -d dave 19197 0.0 1.2 2144 784 ?

S 13:29 0:00 in.telnetd Really nothing other than the X window system and a few xterms. This should not be taking up 40 megs of ram. Eventually, all the memory gets taken up and the system locks up. I recently upgraded from 32 to 64 megs of ram. I don't seem to have any memory problems when I run Lose 95. Other apps also seem to take up memory, and never free it. I just ran Xview and it appears to take up about 2% of my ram, but never give it up. I installed the ram a few months ago and it is not the same brand as the older simms in my board. I did populate the simm sockets in a way that is allowed (2x16 meg simms and 2 new 16meg simms). All of the memory is correctly identified and scanned during bios and Linux boot-up: Calibrating delay loop.. ok - 165.89 BogoMIPS Memory: 62808k/65536k available (772k kernel code, 384k reserved, 1212k data) I have a relatively new mb and PentiumPro 150MHz cpu. So, based on all that, has anyone else experienced this problem? Is there some kernel setting that needs to be complied in that is not obvious? If noone has any software related suggestions, I'll try moving the simms from bank to bank and try replacing it to see if the problem continues. Thanks in advance, dave keeler heyjoe1@lamar.colostate.edu
