> We have been trying to troubleshoot issues with messages not being deleted from the KahaDB store, and have determined that in our case, it is often due to uncommitted transactions. MessageDatabase.checkpointUpdate() logs the location of the first open transaction, but not the filenumber. This patch logs both, to make finding the offending transaction easier.
