Dario,

Thank you very much for your response and clarification.

But you mentioned that the messages are frequently repeated after 10:32, but unfortunately I noticed to many repeatitions before that time.

Further, MetaDataAdapter is the same for both Java client and JavaScript client, so both of them sharing the same NotifyUser method.

The versions that you requested are:

The lightstreamer server version is : Lightstreamer Server Allegro-Presto-Vivace version 5.1.1 build 1623.2
The lightstreamer JavaScript: Lightstreamer JavaScript Client Library version 6.1.1 build 1640 Compatible with Lightstreamer Server since version 5.1

The lightstreamer Java: Lightstreamer Java Adapter Interface version 5.1.1 build 1623.2
Compatible with Lightstreamer Server since version 5.1
