New submission from Hinko Kocevar <hinkoce...@gmail.com>:
I'm running a tornado server with websockets client. Every now and then the python3.5 crashes, seg faults. I added code tracking (https://stackoverflow.com/questions/2663841/python-tracing-a-segmentation-fault) and this is what I see: line, /usr/lib64/python3.5/asyncio/events.py:675 call,
