Hello, I'm developing a tomcat webserver application that uses ElasticSearch 1.0 (Java API). There is a client facing desktop application that communicates with the server so all the code for ElasticSearch is on that one instance and it is used by all our clients. With that being said I am running into this issue: After initializing a new TransportClient object and performing some operation on it, there is a chance that i could sit idle for a very long time. When does sit idle for a long time it gets this error:

I know the ideal situation would be that after every request the transport client is closed. But since it lives on a webserver with lots of search requests coming in, we would ideally like it to stay open because it takes 3-4 seconds for a transport client to initialize and we are going for speed here. Also since we are having one central server to handle all search and index requests, can the TransportClient handle multiple simultaneous requests from different users at the same time? We just want to make sure that we are doing this correctly. -- You received this message because you are subscribed to the Google Groups "elasticsearch" group.
