Hello,

today I was experiencing the following error which unfortunately leads to our application not working properly anymore:

Got unexpected exception for unordered message UNORDERED_MESSAGES in session S5ee5340a8f7199dfT4504720: Error in message forwarding: com.lightstreamer.interfaces.metadata.Notification Exception

Can anybody tell me what is causing that?

Could it be caused by a client that is fast and often switching between http streaming and web socket connection? And why is the client switching all the time (each second) between these modes?

Best regards,
Oliver
