Hello,
I came across not understandable problem connecting transactional pull replication. Once or twice a month I have a problem that stored procedure on subscription server (sp_MSupd) cannot be finished. It is not blocked by any other session and does not have any wait type. It simply hangs and remains in task status RUNNABLE. The only one way to recover the replication is initilizing it from backup or snapshot. Do you have any suggestions. Have you faced similiar problem?
