log from simple test

I have two cameras, one of them not work very well sometimes, but when gst-rtst-server try to connect to bad camera, it can't connect to good camera too. Only when gst-rtsp-server drop connection by timeout to bad camera, it connects to good one. It looks like gst-rtsp-server blocks somewhere.

Simple test:
from gi.repository import Gst, GObject, GstRtspServer
Gst.init(None)
rtsp_server = GstRtspServer.RTSPServer()
rtsp_server.attach(None)
factory = GstRtspServer.RTSPMediaFactoryURI()
factory.set_uri('rtsp://good_camera_url')
rtsp_server.get_mount_points().add_factory('/good', factory)
factory = GstRtspServer.RTSPMediaFactoryURI()
factory.set_uri('rtsp://bad_camera_url')
rtsp_server.get_mount_points().add_factory('/bad', factory)
GObject.MainLoop().run()

From log clearly see that after client to bad camera attached to context and enter mainloop, client to good camera connected, but stack on attaching it to context. And only after bad client exit mainloop, client to good camera start to work.
