Alan, I applied the following patch:
--- linux/net/ipv4/tcp_output.c.orig Tue May 30 23:25:13 2000
+++ linux/net/ipv4/tcp_output.c Thu Jun 1 22:39:25 2000

Running on quad CPU SS-10, Ross RTK-625 Hypersparc, after about an hour
we got a couple of OOPS in apached and then the machine hung.
It wasn't doing this without the patch, though without the patch I did get
an occasional OOPS in swapper followed by machine death.
We've rebooted with the patch still in place and will allow it to run a
while longer to find out if this patch is the casue or not. I captured the
OOP's with a digital camera and will post those after I have time to transcribe
but may be a day or two.
