Description

To reproduce:
1) Start two durable subscriptions using the openwire swissarmy examples:

ant consumer -Dtopic=true -Ddurable=true -Dsubject=test -Duser=admin -Dpassword=admin -Dmax 500000

ant consumer -Dtopic=true -Ddurable=true -Dsubject=test -Duser=admin -Dpassword=admin -DclientId=c2

2) Start a producer using the following command:

ant producer -Dtopic=true -Ddurable=true -Dsubject=test -Duser=admin -Dpassword=admin -Dmax=500000

3) Kill one of the durable topic subscribers and let the test run

4) the broker will go OOM

The cache for the offline durable sub is not recording is cached messages against system memory usage as it should. Hence the limits are not hit.
