particularly in HA configuration, there seems to be issues with closing sockets, and the IOException is fired because the lock for the socket is kept by another thread. This exception is not handled in the stop scenario https://github.com/RestComm/jain-sip/blob/master/src/gov/nist/javax/sip/stack/NIOHandler.java#L508 because we have a silent catch(Exception).

consider to catch Runtime as well and provide at least a WARNING log
