kswapd causing invalid operand 0000 on K6-II with kernels 2.4.16 & 2.4.18. BUG() reports vmscan line 358.
Something to do with LRU's.
The machine has been crashing after heavy network load (not data transfered, but number of opened and closed connections). The last crash was after somebody tried to ftp in as a non-existent user some 150 times. 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.
