Issue

When Fuse is used in a active/passive mode of operation -- that is, multiple stand-alone (not Fabric8) instances of Fuse competing for a start-up lock -- the passive instance will continue to open listening ports until it becomes active. Over a long period of time the passive process could fail owing to a lack of available file descriptors.

Please note that the problem does not arise with master/slave operation controlled by Zookeeper in Fabric8, or when using a master/slave arrangement of A-MQ message brokers controlled by file or database locking -- it is associated only with active/passive locking in Fuse (more specifically Karaf) itself.
