---------------------------------------
Summary: Fails to load journal after queue full
Key: ARTEMIS-2255
URL: https://issues.apache.org/jira/browse/ARTEMIS-2255
Project: ActiveMQ Artemis
Issue Type: Bug
Affects Versions: 2.6.4
Reporter: Ulf Lilleengen
I'm getting an OOM error when loading the Artemis journal after producing
messages until it is 'full'.
The broker is configured with these settings:
* A single anycast address with a single queue
* Address-full-policy = FAIL
* Global-max-size -1 => default to 1/2 JVM heap
After sending a lot of messages, I get the expected error message on the client:
AMQ229102: Address "myqueue" is full.:
ActiveMQAddressFullException[errorType=ADDRESS_FULL message=AMQ229102: Address
"myqueue" is full.]
However, when I restart the broker, it is unable to start due to an OOM when
loading the journal:
2019-02-19 11:23:35,177 ERROR [org.apache.activemq.artemis.core.server]
AMQ224097: Failed to start server: java.lang.OutOfMemoryError: Java heap space
Setting the global-max-size explicitly to 1/4th of the JVM heap fixes the issue
for me.
In order to provide more robust defaults, I think the default should be
decreased from 1/2 to 1/4 of JVM heap.
