The saga of failing connections to my web site. Some do, some dont.
2.1.5 will, 2.2 wont. Anything SUN based also seems to barf. I dont
know about the rest. Some connect and hang. 5000 a month on average
have no problems at all!!!

Well, I admit defeat on trying to get this ;
FreeBSD nanguo.chalmers.com.au 2.2-961014-SNAP FreeBSD 2.2-961014-SNAP #0: Sun Feb  9 08:52:21 EST 1997     robert@nanguo.chalmers.com.au:/usr/src/sys/compile/MYKERNEL  i386
;
working so that connections don't hang.

I have recompiled the kernel with lots of advice from the handbook;
This is my KERNEL config;

#
# GENERIC -- Generic machine with WD/AHx/NCR/BTx family disks
#
# For more information read the handbook part System Administration -> 
# Configuring the FreeBSD Kernel -> The Configuration File. 
# The handbook is available in /usr/share/doc/handbook or online as
# latest version from the FreeBSD World Wide Web server 
# <URL:http://www.FreeBSD.ORG/>;
#
# An exhaustive list of options and more detailed explanations of the 
# device lines is present in the ./LINT configuration file. If you are 
# in doubt as to the purpose or necessity of a line, check first in LINT.

=================================================

I have turned externel caching off. Set the DRAM chip speed to 70ns,
enabled BIOS caching, swapped out an in new ethernet cards, new cable,
enabled PPPD direct from the server. 

combed my hair a different way, held my mouth differently, and
made offerings to the Great God Intel... and not a few others as well.

NADA. NOTHING makes the slightest difference.

IF.... you have any constructive suggestions. I'd like to hear them.
I'd really hate to have to change OS's, as apart from this problem,
FBSD is a great system to work with. and I don't even know if the problem
is a FBSD problem.

cheers,
Bob
