Much easier fix:

vi /etc/sysconfig

#
# Some broken implementations can't handle the RFC 1323 and RFC 1644
# TCP options.  If TCP connections randomly hang, try disabling this,
# and bug the vendor of the losing equipment.
# 
tcp_extensions=NO

If this does fix the problem, I'd like to know why.  Is BSDI's implementation
of RFC1323 and RFC1644 broken or is ours?  Anyone know of some BSDI 2.0 
machines that we can test against?
