Frozen NetStreams and Streams

Hi,
I'm using FMS 3 for republishing Streams to second server. For each Stream is used one NetStream and for every NetStreams is used only one NetConnection. Problem is when Stream is suspended, then NetStream and Stream on second server are still active. Users connected to second server still see the Streams (last shoot) but larger problem is that NetStreams and Streams are still visible in FMS console on second server and I have no idea how destroy them without closing NetConnection.
