I set up a two-node link using tunnel.py, two nodes continuously exchanged data
with each other. Quite often, GNU Radio stopped in one node because of the
following error. Any hints to resolve this problem will be highly appreciated.

Exception in thread Thread-1:
Traceback (most recent call last):
