[1.] One line summary of the problem:
Kernel oops in 2.2.14.
[2.] Full description of the problem/report:
I was running X/Netscape on the machine. Netscape (in its usual way)
proceeded to eat up a significant amount of memory; then it hung. I was
unable to kill the process via kill -9. After looking through
/var/log/messages I noticed the Oops. Unfortunately I rebooted the machine
before running ksymoops. However, the system is modified to never unload a
module and the boot process was the same - so it should be stable.
[4.] Kernel version (from /proc/version):
Linux version 2.2.14 (kevin@delaware) (gcc version egcs-2.91.66 19990314/Linux (egcs-1.1.2 release)) #6 Wed Jan 12 21:20:08 EST 2000
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
