Provide means to limit brokers memory use (RHEL4)
Last modified: 2008-10-06 14:59:03 EDT
+++ This bug was initially created as a clone of Bug #452141 +++
In the simplest case we should just issue session exceptions when client attempt
to do things that would push the broker above a given limit.

Moving target to 1.1 as we don't yet have a good solution for this.

Initial suggested solution is as follows:
On startup broker determines the available system memory. The default policy on
any queue for which an explicit policy is not set is to not go above a certain
percentage of this (else flow to disk or throw exception as usual).

Fixed by r679462.

Fix involves applying a fixed size (but configurable) default policy for queues (--default-queue-policy). Once the total message data on the queue reaches that limit, further publications will be either flushed to disk (if the queue is durable) or failed.
RHTS test MRG_Messaging/qpid_queue_policy_bz452141_bz456667 proves that queue policies (queue max message count and queue byte size) are implemented and tested. (ON_QA->VERIFIED)
