> Key: QPID-6224
> URL: https://issues.apache.org/jira/browse/QPID-6224
> Project: Qpid
> Issue Type: Bug
> Components: Java Broker
> Affects Versions: 0.12, 0.28, 0.30
> Reporter: Keith Wall
> Assignee: Keith Wall
> Fix For: 0.31
>
>
> The BDB store uses JE's Environment.cleanLog() on closing a virtualhost in
> order to ensure that the transaction log is clean, that is the redundancy is
> removed and it occupies as little space as possible.
> JE's javadoc makes specific recommendations about how this method is to be
> used (cleaner thread shutdown and perform a checkpoint), but the BDB coding
> does not heed this advice.
> https://docs.oracle.com/cd/E17277_02/html/java/com/sleepycat/je/Environment.html#cleanLog()
> This has been seen to leave behind very large transaction logs. These slow
> startup time and in the HA case, can mean that nodes are forced to ship
> (network restore) more data than is necessary across the network.
