I have had problems with sessions dropping on the DCA (Racal-Milgo) 355
TCP/IP gateway, when a T-1 circuit has a single error, causing the cisco
serial line to have a "illegal frame address" error. I have set the 
Ethernet interface that has the DCA product on it to "no ip unreachables"
with some success. This is version 5.10 of DCA (Racal-Milgo), which is not
the current revision. I don't know yet if 5.20 has the bug fixed. That's 
the only one that I know of that is not implemented correctly. I have not
found anything in the RFCs that address this scenario of the route being
only momentarily down, but it seems like you wouldn't want to close the
session at the first hint of trouble. :)
