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.
