We had a problem where the Recovery log was not being reset by the Database
backup.
IBM believe that the problem was due to a hung client session which had not
released a thread on the recovery log.
The solution was to upgrade the MVS Server to 3.1.2.15 with fixtest pq21945.
Since applying this fix the problem has not reoccurred.

The Recovery Log having reached the DBBackuptrigger value,
especially
repeatedly, is obviously a symptom of a LOT of activity. What
sessions
were active? What was going on? Look at your Activity Log and
accounting records for client activity.
