Tux-T9 crashes under load



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
root       818  0.0  0.0     0    0 pts/0    SW   12:46   0:00 [TUX logger]
root       892  0.0  0.2  1516  584 pts/0    S    13:05   0:00 grep TUX

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