We are using circular logging. QMGR version V6.0.2.4 on HPUX. This has appeared repeatedly recently:

AMQ7469: Transactions rolled back to release log space.
EXPLANATION:
The log space for the queue manager is becoming full. One or more long-running
transactions have been rolled back to release log space so that the queue
manager can continue to process requests.

The weired thing is, when we check for log files, lasted modification date indicates MQ has not even used up all the primarly logs before throwing AMQ7469.

Today is May 24, and only 2 primary log files has been accessed today, but the transaction has been rolled back due to log space full.

This is our qm.ini setting:
| Quote: |
Log:
LogPrimaryFiles=10
LogSecondaryFiles=5
LogFilePages=16384
LogType=CIRCULAR
LogBufferPages=0
|
Why doesn’t MQ use logs S*1-S*8 then?
Additionally, how to find active logs when using circular logging? We wish to calculate a used-up percentage for monitoring purpose.
Thank you.

What has changed application wise, because the above suggests to me that something is now initiating a UoW that is spanning all your logs?
