Transport: limit number of bytes read
-------------------------------------

                 Key: JGRP-718
                 URL: http://jira.jboss.com/jira/browse/JGRP-718
             Project: JGroups
          Issue Type: Feature Request
            Reporter: Bela Ban
         Assigned To: Bela Ban
            Priority: Minor
             Fix For: 2.7


In the transport, each message is prefixed with its length. If, on the receiver side, we receive garbage data (e.g. a random app connects to the same port), then JGroups tries to interpret the first 4 bytes as length, and this might be quite huge (1.6GB in one instance).
If we know that our packets are never larger than 200'000 bytes, then we can set a flag discard_messages_larger_than="200000". If the flag is 0, no messages will be discarded.
