    For sure, Lightstreamer is not directly involved in the issue.
    However, Lightstreamer adapter interface requires you to be careful when forwarding subscription requests to a database, because
    • subscribe can be called multiple times, even for the same item, if a client disconnects and later reconnects
    • you may need to poll your database in order to supply real time updates

    You might not be sharing the connection properly; or closing the cursors properly.
