I currently have transactional replication set up for three databases from the same Publisher to the same three Subscribers in SQL Server 2005. Publisher and Distributor are on the same server.
One of the databases on one Subscriber stops for several hours each day at different times with no indication of why. No problem with all three databases on the other two Subscribers or the other two databases on the problem Subscriber.
Searching the system logs shows nothing abnormal happening on the Subscriber and Replication Monitor details just says "delivering replicated transactions". Inserting a tracer token shows the Publisher to Distributor is normal.
Any suggestions for troubleshooting this problem?
