Not exactly,
setVolatile sets the lifeTime of the message to 0 and forceDestroy to 
false. It will be cleaned up once it is not referenced anymore. It 
should not be referenced anymore once the last subscriber has become its 
message.

I suggest you should try what Marcel told. When looking at the dump pay 
particular attention at the queues.
