adding
store_avg_object_size 7 KB
to my squid.conf and doing squid -k reconfigure seems to have fixed it
for now.
I am still somewhat amazed that squid would completely lock up, just
because it didn't expect so many small files. I had the harddisk
space set to the default (100M, yes, I am going to change that as soon
as I get a bigger hd for the machine) with about 90M used for the
cache.
The expected behavior would have been of squid to just kick the old
stuff to make room for new data. It appears to me as a bug that it
just won't work anymore.

You appear to be making your chroot environment more and more complex,
which makes it harder and harder to fully secure.
Why not:-
1. Static link your program. That definitely rids you of
needing a pile of internal library images. It means
you have to recompile for even minor updates in the
supporting libraries, but thats a similar degree of
work to upgrading the libraries within your chroot
jail.
2. Don't attempt to use a named pipe connection - too
much like hard work and a potential for desecuring
your server
3. Make the program do its DB connections to 127.0.0.1
[ie loopback] - no serious performance hits since it
doesn't hit the real network, and that IP is always
your local machine. No DNS libraries needed at all
[although they are probably linked in by step (1).]
nor additional DNS config - ie /etc/resolv.conf &
/etc/nsswitch.conf

Gary,
If I understand your post, do the following:
1) I'm going from memory for RH5.2... edit /etc/mail/relay_allow, or
ip_allow, or name_allow and add the network address for your internal LAN.
Sendmail uses this file to determine who is allowed to relay off of this
server. By default, RH configures sendmail to NOT allow relaying except from
the localhost, which is a good thing. You don't want the spammers of the
world to find your IP address and use your server to spew 10000+ emails off
of your server.
2) If you want to relay email to your ISP's email server to perform the
final delivery of all email, edit the following line in /etc/sendmail.cf.
You don't have to though, sendmail can deliver all email for you. But as the
other poster to this thread mentioned, some sites may reject email from your
server because of a MX or in-addr.arpa mismatch. So far, I have not had any
rejected and I have been using Linux/sendmail for a couple of years now.

Sigh... The *point* is that diald does not magically know when
you "want to browse the Internet". It only knows about packets
that are routed over its link. If it sees packets that match
its filter rules it brings the link up. If it continuously
brings the link up it is because it is seeing such packets.
There are many ways of finding out what those packets are.
Two of the more obvious and useful are to use diald's excellent
debug option or to use tcpdump. The least useful is to have
some third party guess what is happening. Once you know what
the packets are and where they come from you can worry about
how to fix it.

WHAT ???
A Cisco router is ok (we have one too), but paying over 1k$ is for s.th.
like a router is far too much !!!
We have a firewall (it is routing too of course) with RH 6.0 on a 486DX2-66
Box (32MB), which is oversized.
It is working great !!!
If you have old boxes go and get Linux...
FreeBSD is same good, but you get better infos on Linux.

The objective is to be able to do most sysdmin fonctions remotely
