I am working with SQL server 2008 on Transactional (peer to peer) replication.I am facing an error "The replication agent has not logged a progress message in 5 minutes. This might indicate an unresponsive agent or high system activity. Verify that records are being replicated to the destination and that connections to the Subscriber, Publisher, and Distributor". I cannot reinitialize the subscription because it is peer to peer topology.

Does anyone know what is this mean and how to fix this?
Thanks in Advance..
