Affected version: AMQ 4.1.2
org.apache.activemq.broker.region.Queue send(ConnectionContext, Message)
method always throws ResourceAllocationException if sendFailIfNoSpace is
set, producerFlowControl is enabled, message response is not required and
network connection is not used to connect to broker.
In this case thread execution ends up in following code block:
...
} else {
if (usageManager.isSendFailIfNoSpace() ) {
throw new javax.jms.ResourceAllocationException("Usage
Manager memory limit reached");
} else {
while( !usageManager.waitForSpace(1000) ) {
if( context.getStopping().get() )
throw new IOException("Connection closed, send
aborted.");
}
}
}
... usageManager is never checked for space prior to throwing
ResourceAllocationException("Usage Manager memory limit reached"), and no
message can be sent to this queue, regardless of the usageManager set on
queue.
