Hi,

I checked the log and I can confirm that indeed at 14:36:44 the Lightstreamer server experinced a fatal error in the comunication with one of the Adapters:

26-Mar-18 14:36:42,343|ERROR|rs.remote.data.RemoteDataProvid er|#3 Request Sender |Exception caught while unsubscribing from item 'tickbytick_stock125': Connection closed while waiting for an answer to request d740000016260f71118

And since you choose non-robust proxy adapters as a consequence the Lightstreamer server shut down.
To figure out what was the problem is quite difficult but, given the first error message, a hypothesis is that a subscription request (for the Item 'tickbytick_stock125') has caused a crash in the Adapter.
