It certainly worked before.

Not sure what is going on, but it appears that the second attempt to start the kernel would succeed. This might be related to a warning message Address already in use from command line, but I am not sure what is going on here.

This is not the case for the live server.

To reproduce, go to https://vatlab.github.io/sos-docs/doc/user_guide/sos_javascript.html, click edit, and then run the first two code cells. Running the docker image directly could also reproduce the problem.

Whatever the problem could be with the docker environment, sos should generate proper error messages, but it simply hangs in this case.

The problem was the missing feather library for R....
