    Indeed, the db connection is not initialized at the time of
    executing event_route[htable:mod-init]. This is executed after all
    modules are initialized, but the sqlops connections are initialized
    in child init.<br>
    <br>
    However, it should not cause this crash. What version are you using?
    Because latest master and 4.1 have a simple condition at
    sql_api.c:257.<br>
    <br>
    Cheers,<br>
