-----------------------------

LevelDB has been deprecated and is no longer supported.
> erroneous temp percent used

> Key: AMQ-5235
> URL: https://issues.apache.org/jira/browse/AMQ-5235
> Project: ActiveMQ
> Issue Type: Bug
> Components: activemq-leveldb-store
> Affects Versions: 5.9.0
> Environment: debian (quality testing and production)
> Reporter: anselme dewavrin
>
> Dear all,
> We have an activemq 5.9 configured with 1GB of tempUsage allowed. Just by
> security because we only use persistent messages (about 6000 messages per
> day). After severall days of use, the temp usage increases, and even shows
> values that are above the total amount of the data on disk. Here it shows 45%
> of its 1GB limit for the following files :

> The problem is that in our production system it once blocked producers with a
> tempusage at 122%, even if the disk was empty.
> So we invesigated and executed the broker in a debugger, and found how the
> usage is calculated. If it in the scala leveldb files : It is not based on
> what is on disk, but on what it thinks is on the disk. It multiplies the
> size of one log by the number of logs known by a certain hashmap.
> I think the entries of the hashmap are not removed when the log files are
> purged.
> Could you confirm ?
> Thanks in advance
