This is probably the critical piece of information - the TCP connection
has stopped transferring data for some reason and the rdump is blocked
waiting to send.

Unfortunately, you need the last packets that were exchanged in order
to identify which end has the problem (and hopefully provide some
pointers as to why).  If possible, can you repeat the dump whilst you
run a tcpdump on the rdump flow and then post the last dozen or so
packets in each direction.

Please excuse any delays as the result of my ISP's inability to implement
an MTA that is either RFC2821-compliant or matches their claimed behaviour.
