Thomas,
We can connect and do queries and index processes just fine. The problem we
are experiencing is that after a long time of idle (15 minutes or so) doing
nothing, when we go to perform another operation this occurs.

As per the documentation Client is threadsafe and is suggested by the
elasticsearch team to use the same client instance across your app.
Considering your exception above you might need to look your configuration
first (like cluster name and host/port) and you should use port 9300 for
the Java API. Finally, check whether you are under a firewall or something
and you block 9300 port.Hope it helps

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:Mar 08, 2014 1:15:37 AM org.elasticsearch.client.transport

Is there any way to prevent this from happening? 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.
