Hi Sinisa,
The ADJ Resolve process is a process in charge of resolving adjacencies for IP packets received by the CMTS. Basically, when a packet is recieved, the CMTS looks for the destination address in an adjacency table to fast-forward the packet. If there is no adjacency entry, the packet is sent to the RP and the ADJ Resolve process tries to populate the adjacency table (using ARP). If ARP reply is received, the adjacency is created and subsequent packets can be fast-forwarded. If not reply is received, the process retries a few times. During that time, incomplete ARP entries will probably be seen in the CMTS.
I hope this is the explanation you were looking for.
Best regards.
