[CLUE-Tech] Memory woes

[Mike Staver]

Occasionally, I keep logging onto my linux box only to find most of my
services have stopped.  This has happened about 3 times in the last
month, and it's concerning me more and more.  I have 1.2 gigs of memory
in this machine, and about 512 megs of swap.  More than enough I would
think.  I'm running Red Hat 7.3 with the latest red hat build of
2.4.18-5.  I have found out what caused the services to shutdown when I
ran dmesg:

Has anyone else had similar problems with the 2.4.18-5 kernel, or more
specifically, the Red Hat builds of this on 7.3?  By having 1.2 gigs of
memory and that swap space, I thought for sure I was safe.
