P5-100Mhz
32Mb
1.2Gb EIDE disk
WD8013 Ethernet card
Asus mainboard
Debian 1.1
This machine is basically our nameserver, NIS server
and runs msql and apache (for management functions only)

Linux 2.0.27 (dth@troi) (gcc 2.7.2) #1 Thu Dec 5 22:50:28 MET 1996 [troi]

Twice within the current uptime we had this kernel message:

free_one_pmd: bad directory entry 80000000

At this point certain processes get killed.
Yesterday it was bind, previous it was apache and NIS.
Just restarting the "missing" processes makes everything work
like normal. Prior uptime (2.0.23 kernel) was more than 60 days.
Sudden death (probably ping_of_death) made us install 2.0.27.

Anyone some ideas ?
