Hi Patrick,

Please, could you replicate the issue, in a test environment, after setting the "LightstreamerLogger.pump" and "LightstreamerLogger.subscriptions" loggers to DEBUG level in the "lightstreamer_log_conf.xml" configuration file?
In this way we can check out the update processes in the Lightsreamer server and the list of updated field values sent to the client.

Please also note that with these logging configurations, the log file could reach huge size.
