tmpDB.data file grows irreversibly
----------------------------------
Key: AMQ-3713
URL: https://issues.apache.org/jira/browse/AMQ-3713
Project: ActiveMQ
Issue Type: Bug
Components: activemq-camel
Affects Versions: 5.4.2
Environment: linux, windows
Reporter: Sree Panchajanyam D
Steps to replicate
On a queue, produce non-persistent messages(message size can be 1Kb to 5kb )
with consumer down. There will be an increase in db-*.log files along with this
there is an increase in the size of tmpDB.data file. Let the temp store
percentage grow up to 90% without triggering the consumer. Once the temp store
is 90% start the consumer. The log files are deleted once the messages are
consumed but tmpDB.data file does not decrease in size and this causes the
temp store to be 60 - 70% full.
Issues with this with slow consumer, which does not call for a producer flow
control, temp store % keeps growing and at one particular point of time hits
100% just because of tmpDB.data file and hence no messages can be produced on
to AMQ without a restart of it.
In my case this situation occurs very quickly when one of the consumer goes
down as the load on AMQ is high.
The above is the case with persistent store as well. Please suggest a solution
or provide a patch for this problem.
