Category: JBossMQ Group: v3.2 Status: Open >Resolution: Later Priority: 5 Submitted By: Tim McCune (javajedi) Assigned to: Nobody/Anonymous (nobody) Summary: Multiple queue receivers can starve Initial Comment: In BasicQueue.java, receivers is a HashSet. The code iterates through this set to determine who to give the next message to. If there are multiple receivers listening to a single queue, most of the receivers will starve because the receiver who happens to have the lowest hashCode will keep jumping to the front of the iteration order. A simple fix of changing receivers from a HashSet to a LinkedList (1 line change) causes the receivers to get equal distribution of messages. I know this behavior is left up to the implementor in the JMS spec, but don't you think using a list makes much more sense? ---------------------------------------------------------------------- >Comment By: Elias Ross (genman) Date: 2004-07-31 12:34 Message: Logged In: YES user_id=556458 You can set the implementation of Receivers in the Destination, the MBean attribute is called "ReceiversImpl" and can be set to a linked list or array set implementation.
