I have a Debian box which has been rock-solid in the three years I've been using it. Currently it's slink with the 2.0.38 kernel (custom-compiled) and just a few extras in /usr/local. No other OS.
Until recently it had just 32MB of RAM. I added 64 more on Saturday. Everything seemed fine to begin with---the 96MB was detected in BIOS and by the kernel; I had much less disk-thrashing in long Netscape sessions and so on. But .... If I leave the machine up overnight (as has been my habit) with nobody logged on and only cron jobs running, when I log on again in the morning, `top' tells me that almost all of the memory is in use, and when I try to work, I get constant segmentation faults (especially in resource-heavy applications like emacs, TeX, X ...) and sometimes a kernel-panic. Rebooting `fixes' the problem. The hardware: Pentium 2 (233 with 512K cache), an Asus P2L97 AGP Motherboard, Quantum 4.3GB SCSI Hard Drive. Are there tools available that would help me diagnose the problem and hopefully solve it? Thanks in advance for any advice, Jim McCloskey
