Pure Master Slave broker hangs when storage limit is reached
------------------------------------------------------------
Key: AMQ-2564
URL: https://issues.apache.org/activemq/browse/AMQ-2564
Project: ActiveMQ
Issue Type: Bug
Components: Broker
Affects Versions: 5.3.0
Environment: Ubuntu 9.10 Desktop, Java 1.6 (build 1.6.0_16-b01)
Reporter: Jörn Kottmann
Priority: Minor
The pure master slave broker hangs when the storage limit is reached and
dequeueing messages from the queue is not possible.
The behavior can be reproduced with a producer which sends messages to the
master broker until the slave broker writes
"INFO | Usage Manager Store is Full. Stopping producer
(ID:karkand-51292-1263305705067-0:0:1:1) to prevent flooding queue://TestQueue.
See http://activemq.apache.org/producer-flow-control.html for more info"
this message to the console.
To reproduce the store is full message on the slave broker maybe 2 - 3 attempts
are necessary otherwise
the messages appears on the console of the master broker.
Any attempts by a test consumer to dequeue messages fail, it just hangs.
The following information gather with JMX might be interesting:
MASTER: StorePercentUsage=99
SLAVE: StorePercentUsage=100
The attributes for the Queue are identical on both
brokers.
