The big difference between topics and queues is that for queues, if

the message store. This is only true for topics if a durable
subscriber exists and is interested in that topic.
Which is not good. If many messages are added to the topic without
being
taken off from the broker by consumers, the memory is soaked up
quickly,
OutOfMemoryErrors occur, and the whole application gets corrupted. If
the topic is too full, ActiveMQ should start to swap messages to
external memory (disk). Sure, performance would be degraded but at
least nothing will break.
