There is no current event loop in thread and process already finished, ignoring input

Hi !

On the version 1.10-rc2, (and also on an older version), I have king of this message in the server log file whereas the web interface is always running (when I click on the button STOP, it doesn't work, the process still continue to running, but in fact, the log file tell the opposite).

RuntimeError: There is no current event loop in thread 'Thread-16'.
Exception in thread Thread-15:

Could I tell you other things which could help you to resolve this problem?

Thank you !

Hi @csphoenix1, thank you for the report. Please have a look at #105
This is a problem with Tornado 5.
For the temporary solution, please replace src/server.py file with https://github.com/bugy/script-server/files/1864885/server.zip

In master branch the issue is already resolved, but I believe I have to cherry-pick it to release as well
