New Revision: 955370

URL: http://svn.apache.org/viewvc?rev=955370&view=rev
Log:
Bug 603835 - cluster_tests.test_management failing.

Clean up connections causing extra connection objects in the mangement agent map.
- update connection was not being closed.
- connections belonging to members that left the cluster were not fully cleaned up

Also fixed test errors making failover_soak fail sporadically.
