Fabric Port Service not cleaning up ports properly

Start a fresh 6.3 or 6.2.1 R4 and follow these commands: fabric:create --clean --wait- for -provisioning --profile fabric profile-edit --feature fabric-zookeeper-commands fabric zk:list -r /fabric/registry/ports/ip # check what ports are reserved zk:get /fabric/registry/ports/ip/<ip> profile-create port profile-edit --pid org.ops4j.pax.web/org.osgi.service.http.port= '${port:8501,8544}' port container-create-child --profile fabric root child list = [1 2 3 4 5 6 ]; each ($list) { container-add-profile child port ; sleep 3000 ; container-remove-profile child port ; sleep 3000 } # watch Pax-Web starting up on new ports all the time # note how many ports of the range [8501,8544] are blocked now zk:get /fabric/registry/ports/ip/<ip> container-delete child zk:get /fabric/registry/ports/ip/a185977e84c7 # only the ports currently in use by the deleted container got removed from list. All previous ports are still blocked, slowly exhausting the port range, but won't be used at all by any containers.
