You can send a private message to me or to Mone through this forum.
Alternatively, if no private information is included in the log, you can send the log as an attachment to your next post.
As the last resort, please write to support@lightstreamer.com

Is it possible that you open multiple engines in your application?
Otherwise, we need more information to proceed.
Please ensure that the "LightstreamerLogger.connections" category is set as DEBUG in the Server log configuration file when you get the log.
