Issue: 

Some records from a store are stuck in the replication monitor which is never being replicated to Enterprise.

Steps: 

Restarted the server, the configuration manager and Replication service however the issue remains the same.

New records are processing fine only issue with some specific records was there.

Resolution: 

There can be multiple reasons for such cases however one of the reasons can be the wrong date on the store database server.

In this specific case, the store server had a date 2009 which was causing the issue. So once the date at the store server was corrected , stuck replication records started moving and replicated to HO successfully.
