Hi. I have opencv 3.0 running on raspberry pi. A python server is running with one thread capturing frames continuously.Once a minute another thread captures one frame and a 10 sec video. This is done using the opencv camera.capture splitter port. The program crashes with in a couple of days when doing all 3. After turning off video capture, the program ran for 20+ days and finally crashed with the following stack trace.
Please let me know if there is anything anyone of you can suggest.
