    Hi from the log, it looks like you are using version 7.9.0 of gatord, but recompiled to report that it is version 8.0.0, presumably so you can use it with a later version of Streamline?

    This is not explected to work; please first retry using the binary provided with Streamline 8.0.

    Thanks, Ben
