Add note about known issue to release notes for EAP 6.1.3:

"Periodic recovery on committed transactions" - bz#1009981:
When the server is under an excessive load, the server's log may contain messages like those below, indicating that a transaction rollback had occurred.

----

Under heavy load, the processing time taken by a transaction can overlap with the timing of the periodic recovery process's activity. The periodic recovery process detects the transaction still in progress and attempts to initiate a rollback but in fact the transaction continues to completion. At the time the periodic recovery attempts but fails the rollback, it records the rollback failure in the server log. This error has no affect for data integrity.
Comment 2 Scott Mumford 2015-03-26 03:59:33 UTC 
The release notes for micro releases typically aren't prepared by the docs team. 
Pinging Jimmy to see if he can take/redirect this appropriately.
