I had a similar problem with a session to a cisco router that got dropped
after a few minutes because of missing keepalives. After a hour of
analizing tcpdump outputs it turned out to be a duplex missmatch on the
way to that router. The initial full table dump of the cisco caused
massive packetloss and retransmits and finally the session timed out
because of this.
Check /var/log/daemon for the cause of the drop and have a look at "netstat
-s -p tcp".
