Package: x2gobroker

When using python2-tornado >= 5.0 with the latest x2gobroker the
x2gobroker-daemon does not start and following error message is
shown in the log files:

Traceback (most recent call last): File "/usr/bin/x2gobroker-daemon", line 306, in <module> launch_ioloop() File "/usr/bin/x2gobroker-daemon", line 281, in launch_ioloop tornado.ioloop.IOLoop.instance().start() File "/usr/lib/python2.7/site-packages/tornado/ioloop.py", line
939, in start raise RuntimeError("Cannot share PollIOLoops across processes") RuntimeError: Cannot share PollIOLoops across processes

This issue was tested against tornado versions 5.0.2, 5.1.0 and
5.1.1 and this error always occurs. The last working version of
tornado is 4.5.3.

Kind regards, Niels

Please let us get this fixed with the version of x2gobroker you find
in the nightly builds.

It is very likely, that you will encounter the same issue when using
x2gobroker from the X2Go nightly builds, but that version should be
the one to use for testing setups, as it will be release soon.

And before the release, we should get your problem solved.

Thanks+Greets, Mike
