Hi Team, We have a 3 node server cluster
A 4th node joins as a client with a continuous query on a Table A( Transaction_mode = transactional ). Now If I bring the client down and issue an update to the Table A within failureDetectionTimeout 30000 , I get the following error and */this error brings the server down/*: "(err) Failed to notify listener: GridDhtTxPrepareFuture Error" =================================== Basically the server , tries to update the record on the Table A, and tries to notify Client since it had registered a continuous query for Table A. But since the Client Node has been brought down, and it undeploys the remotefilterfactory lambda, and the server is no longer able to complete the transaction . */This also brings the server down./ * How can I resolve this issue ? ======================================= Please find the complete stack trace for this error : [12:14:12] (err) Failed to notify listener: GridDhtTxPrepareFuture
