David,
It sounds like you are running into ARP cache timeouts.

The p4200 default is to timeout an ARP table entry after 5 minutes.
The p4200 won't deliver a packet if it has to ARP for the host: it
will drop the packet and do the ARP, relying on the end-to-end protocol
to retransmit the dropped packet.

The good news is that the ARP timeout values are configurable.  ARP
is Protocol 3 in the p4200s.
