hello, we get a lot of these errors which I noticed fairly recently. Their number increased quite a lot, so they could not be ignored. What could be the reason fot this: RTPMulticastListener.unbind: java.net.SocketException: error setting options ERROR server comment 2011-08-10 16:59:00 195627118 127.0.0.1 - 0 0 160.375 - - - - - - - - RTPMulticastListener.unbind: java.net.SocketException: error setting options ERROR server comment 2011-08-10 16:59:00 255730124 127.0.0.1 - 0 0 160.375 - - - - - - - - RTPMulticastListener.unbind: java.net.SocketException: error setting options ERROR server comment 2011-08-10 16:59:00 588509360 127.0.0.1 - 0 0 160.375 - - - - - - - - RTPMulticastListener.unbind: java.net.SocketException: error setting options ERROR server comment 2011-08-10 16:59:00 894381808 127.0.0.1 - 0 0 160.39 - - - - - - - - RTPMulticastListener.unbind: java.net.SocketException: error setting options ERROR server comment 2011-08-10 16:59:00 20372047 127.0.0.1 - 0 0 160.406 - - - - - - - - RTPMulticastListener.unbind: java.net.SocketException: error setting options ERROR server comment 2011-08-10 16:59:00 1721551192 127.0.0.1 - 0 0 160.453 - - - - - - - - RTPMulticastListener.unbind: java.net.SocketException: error setting options ERROR server comment 2011-08-10 16:59:01 741799009 127.0.0.1 - 0 0 160.546 - - - - - - - - RTPMulticastListener.unbind: java.net.SocketException: error setting options ERROR server comment 2011-08-10 16:59:01 1808190327 127.0.0.1 - 0 0 160.562 - - - - - - - - RTPMulticastListener.unbind: java.net.SocketException: error setting options Thanks! ---
