async_network_io wait during replication

I have re-initialize some subscription. After generated snapshot successfully, the synchronization view showing 'The process is running and is waiting for a response from the server.' and I found the replication process is under 'async_network_io wait'. The job has run for more than 8 hrs. Any idea to improve it? Thanks in advaise.

Are you running the sync agent (like merge agent/distribution agent) in continuous mode? If yes, it will show running forever, although the submitted transactions/commands have been replicated, agent job is just keeping waiting for next actions.

Thanks

If an continuous sync complete for a session, its current history log usually shows something like "No replicated transactions are available" and sync job is still showing as running.

As for your case, could you open sqlmonitor to check the current status for the job, is it still running or fail already? If it's running, what's the current history shown? Does the history get updated every a few minutes?
