asterisk users - Jun 2009 - Asterisk eventually fails when connection dies

I have a single server running asterisk 1.6.0.8 with a few sip voip providers
and a tdm card for redundancy. It has a caching name server and the sip
providers
are hard coded in the hosts file.

When the internet connection dies, it fails over to the dahdi channel as it
should, but slowly the sip phones loose registration and the incoming dahdi
channel can still answer the incoming call, but it doesn't pass it off the
mailbox, it just says the "person at extension... is not available"?
There
is a custom recording setup that otherwise works?

What does a guy got to do to keep asterisk up when the net connection fails?
This is becoming a show stopper :(

Thanks!

A persistent local DNS cache such as pdnsd[1] or djbdns[2] could help.
