Cannot find the identity range allocation entry for the Subscriber

Dear All,
When I am synchronizing the merge push subscription, receiving following error
Cannot find the identity range allocation entry for the Subscriber in the
MSmerge_identity_range table. Reinitialize the subscription.
What could be the cause of message, and is there some way so I can avoid
re-initialization of susbscription
How did you deploy this subscriber? Did you do a no-sync?
