The FRS Journal File is corrupted, erased, or overflowed. FRS replication is stopped until this can be fixed.
For more in-depth monitoring of SYSVOL and FRS, download and install the Ultrasound tool from the Microsoft Web site at http://go.microsoft.com/fwlink/?LinkId=25827. Ultrasound shows health ratings and historical information about FRS replica sets. You can use it to monitor the progress of replication and to detect problems that can cause replication to become backlogged or stop. Ultrasound also provides detailed views for troubleshooting and a framework that you can use to customize alerts and views for your organization.
