Hi Kurt,

We struggled for a long time with problems that somewhat resemble yours.

It turned out to be some kind of hardware problem in the slow speed serial
boards of the p4200.  As I recall the receiver side of the USART chip went
deaf until it was reset as the result of a maintainence test failure.
The t 2 process offers some clue that the tests are failing.

While the chip was deaf, routes would be dropped and unreachables would
be issued.

If your Proteon person can't help, I'll put you in touch with mine.

Ross
