      Setting e.g com.arjuna.ats.arjuna.hornetqjournal.poolSize=20 may provide limited relief, but is considered a guideline rather than a rule by older versions of the journal. Newer versions (2.14+) of the journal have an actual fix by adding backpressure from the file cleaner

      Description

      Under sustained high load the HornetQ (Artemis) Journal store creates new store files instead of recycling old ones. Whilst bounding write latency this will, over a prolonged interval on sufficiently fast storage media, lead to excessive use of storage space. For our use case it's preferable to have the journal generate write-throttling backpressure from the file recycler.  ref https://issues.apache.org/jira/browse/ARTEMIS-2837
