You could try a 2.6 kernel, if you are still on 2.4 or trunk if you still use 8.09, maybe those parts changed in the meantime. Besides that, I would suggest to kill mjpg-streamer from time to time and restart it with a different output directory. > > bcm47xx_wdtWatchdog will fire soon!!! > > This is the very last message, the system does not respond any more. > I think this situation should be handled correctly. > > Thanx > K.
