Most of the time, the issues reported on GitHub or in the mail we receive are perfectly fine, don't worry. We love to hear from you in any case, so don't take the following too seriously ;) We'd still like to give some ideas on what information you can include when you report errors for VerneMQ.
We have been asked to include more debug logs in VerneMQ. We'll do that in a next release (it's all nicely included already, but we just don't call `lager:debug` that much). The reason for that is simple: In an Erlang system you mostly use tracing not debug logging.
