Aside from the `user_featurization` issue, I am having a similar problem and wrote about it in this thread here: ["There was an error loading messages and polling has been stopped."](http://forum.rasa.com/t/there-was-an-error-loading-messages-and-polling-has-been-stopped/42395)

My Rasa version is 2.4.0 and Rasa-X is 0.38.1 which are compatible.

@RGK do you have other instances where the conversations are not affected and the `since` parameter is set to a number other than `0`?
