Hi,
Thanks for reporting this issue. The expected behaviour is indeed the one you described: the bokeh webapp backends should be restarted but it is not the case. The issue is now logged in our backlog.
That being said, it could be interesting to try to understand why the backends of those bokeh webapps are stopped by looking at the logs (both the corresponding webapp backend logs and the main DSS instance backend log) when you see that such an issue happens.
Regards,
