I using ElasticSearch 1.1.0 server. I have a Java Web Application that connects to ElasticSearch using Transport Client, i am also using elasticsearch 1.1.0 client. When the application starts it is able to connect to elasticsearch server and all the searches work but after every couple of hours(This happens randomly) the application stops working/not able to execute search on elasticsearch. When i enable client transport and netty transport trace i see following exception. Has anyone seen this issue before, do you have any suggestions ?
