You have to remeber. Concurrent processing of large messaging in the messaging system queue could lead to out of memory errors due to heap being exhausted. A message is considered to be #large# if it exceeds the threshold for large messages. In order to be processed, the message must have a specific number of permits (the number of permits is the message size divided by the threshold).
