The machine has been crashing after running for between 12 and 24
hours. The manner of the crash is different between 2.4.16 and 2.4.18,
but the cause seems to be the same. With 2.4.18 all programs would
terminate (or segfault) and no new programs could be started (or users log
on). With 2.4.16 the machine simply freezes on the terminal, although ssh
still connects, no users can log on.
At first I thought that the new memory manager in 2.4.18 was at fault and
downgraded to 2.4.16, but the same error seems to occur, although it seems
more stable.
I am running a stock kernel 2.4.16 on a K6-II/450. The motherboard is a
Tekram P5T30-B4. I am using the onboard IDE controller for the primary
drive, and a Promise Ultra66 for a second drive. Both use ext2, and a dos
partition is also mounted. The sound card is a Sound Blaster PnP / AWE
32. Networking card is a 3c509.
