are related to the same issue: the remote adapter was too slow in answering to the server
This is the same issue you discussed with Giuseppe here.
From his post:
Please could you confirm if your unsubscribe method implementation is particularly heavy and, maybe, it requires calls to external components? Please note that in a case such your, with Remote adapters and several hundreds of calls involved, just only a processing time of few tenths of a second may result in significant delays.
Since one of our suspicions is that the server remains for a long time waiting for answers from the Metadata Adapter, a first possibility of change in the Lightstreamer server configuration, in order to mitigate the issue, is to increase the size of the SERVER thread pool.
A first suggestion would be to raise it to 100. Please refer to <server_pool_max_size> parameter in "lightstreamer_conf.xml" configuration file.

This means that the socket of the specified session was closed.
This might be a problem with the network or simply a client closing down.
