Is anyone else seeing this bug:

Nov 1 10:24:03 porsche kernel: TCP: **bug**: copy=0, sk->mss=0
Nov 1 10:24:16 porsche last message repeated 17 times

This is on a 486/100, 128 megs of ram, running with 13 virtual
WWW and e-mail hosts.

Also, we are seeing httpd crashing often. From the error logs,
we had this JUST TODAY:

[Fri Nov 1 02:20:08 1996] HTTPd: caught SIGSEGV, dumping core
[Fri Nov 1 04:54:13 1996] HTTPd: caught SIGSEGV, dumping core

This is using NCSA httpd 1.5.2.

porsche:/var/log/httpd> uname -a
Linux porsche.autobahn.org 2.0.24 #2 Wed Oct 30 06:15:40 PST 1996 i486
porsche:/proc> uptime
11:39pm up 2 days, 17:05, 5 users, load average: 0.04, 0.08, 0.08

Ethernet card is a 3c509.

I'm not sure what information to include. There's so much
more information I could include, if anyone is interested.

Take care,
