Hi finodex,

Thank you for providing us with the video that makes your scenario clearer. From the video it seems that regular updates with timestamp 12:58:xx are displayed but after few seconds these fall back to values with timestamp 12:49:xx. It is possible that the Market Data table is statically initialized then due to network disconnections all the Lightstreamer updates are lost?

By the way, if you can replicate the issue in a test environment a snippet of server log corresponding to an evidence of the issue will be very useful.
Please send us <support@lightstreamer.com> the Server log snippet after temporarily setting in "lightstreamer_log_conf.xml" the "LightstreamerLogger.subscriptions" and "LightstreamerLogger.pump" loggers to DEBUG level (note that the log may be very huge).
