Package: x2gobroker

Version: 0.0.3.4 (0x2go1+git20180206.1037+8)



When using python2-tornado >=3D 5.0 with the latest x2gobroker the x2gobrok=
er-daemon does not start and following error message is shown in the log fi=
les:



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 s=
tart
    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 t=
his error always occurs. The last working version of tornado is 4.5.3.




Kind regards,
Niels
