Tux-T9 crashes under load

[Phillip Ezolt <ezolt perf zko dec com>]

Hi All,
	Tux appears to have a problem under load.

When running the SPECWeb99 workload against linux-2.4.2-tuxT9-kgdb, it
crashs in the middle of the test.

The logger remains, and the only hint of the problem is in /var/log/messages.

[root@oaxao linux]# ps -aux | grep TUX

Linux oaxao.zko.dec.com 2.4.2-ac20 #3 Mon Mar 19 12:14:12 EST 2001 i686 unknown
