Alex Rudyy updated QPID-8168:
-----------------------------
Fix Version/s: qpid-java-broker-7.1.0
> [Broker-J] Broker should flow to disk transient messages when heap usage
> reaches critical threshold in order to avoid running of heap memory due to
> consumption of heap by transient message metadata

>
> The flow to disk is currently triggered when direct memory usage reaches
> predefined threshold ({{broker.flowToDiskThreshold}} which is set to 75% of
> direct memory size by default). However, in some situations (for example,
> when direct memory size is big and heap memory size is small), the direct
> memory threshold is not reached but the heap is fully occupied by transient
> messages data, the broker runs out of heap memory.
> The broker behaviour can be improved by triggering flow to disk when a heap
> occupancy reaches the critical threshold in addition to direct memory usage
> threshold.
