LSClient.ForceUnsubscribeTable Method

Tries to unsubscribe from a table for which a previous unsubscribe has been called but an exception has been received. In this case, a zombie subscription may have remained in the Server. This call does not affect client behavior, but the client can try it in order to force a new server side unsubscription attempt. If the call succeeds, a zombie subscription has been indeed eliminated. 

The method is blocking; it returns only after receiving the Server answer upon the request submission. See OpenConnection for details on timeout settings. This kind of request is not included in a batch.
