Description
https://issues.apache.org/jira/browse/AMQ-4638 sets the usage limit of a store to only the available disk space. It does not take into account that the store itself is using space on the disk.
In our environment the store was taking 30 GB of space and there was 17 GB free on disk. Therefore, on startup the store was limited to 17 GB; where it should have been limited to 47 GB. Because of this, by design, no new message can be added to the queue.
