[jira] [Created] (AMQ-4311) Large transaction that contains lots of penging messages can cause OOM

SuoNayi created AMQ-4311:
----------------------------

             Summary: Large transaction that contains lots of penging messages can cause OOM
                 Key: AMQ-4311
                 URL: https://issues.apache.org/jira/browse/AMQ-4311
             Project: ActiveMQ
          Issue Type: Improvement
          Components: Broker, Message Store
    Affects Versions: 5.x
            Reporter: SuoNayi
             Fix For: 5.9.0


Currently MemoryTransactionStore is used to hold pending messages in a transaction.
More pending messages in a transaction more memory is consumed.
Because the message size of pending messages is not counted in usage limit before they are committed so PFC wont block producers as well and large transaction will cause broker throws OOM at last.
