I'm running 2.2.9 (with a redhat 5.2 distribution) on a dual PII machine
with 512Mbytes of RAM and got the following kernel Oops while running two
processes that, between them, used pretty much 512Mbytes of RAM (the
machine also has 1Gig of swap).
The machine was still running after this Oops with a load average of 3.00
(!!), although the process list didn't indicate any processes active, the
two jobs had just gone idle, but kswapd had gone into a zombie state,
which seemed odd.
Here's the relevant entries from the syslog (I'm also running autofs for
user home spaces as you will see from the syslog).
Any thoughts as to what could be causing this?
