DC was patched with the 9.62 patch. The problem appears to be the arp table size. With no TCP/IP connections, all arp resolves find an existing entry in the table. As soon as the PC connects to the Rabbit, resolve starts reporting OBSOLETE for all the entries in the table. And every time the Rabbit sends data, resolve_check fails and it starts a new arp resolve. This continues for a while until resolve eventually is not able to resolve and the socket is aborted.
 

 The size of the arp table is set in net.lib:
 

 #define ARP_TABLE_SIZE    (5*(USING_ETHERNET+USING_WIFI)+IF_MAX)
 

 I'm guessing that it evaluates to either 5 or 10, depending on the value of IF_MAX. 
 

 I added my own arp table size define and set it 20.  So far the Rabbit has been running for 30-minutes with no disconnects.
