server stop responding in few hours due to CLOSE_WAIT

[Jonty Rhods]

Hi All ,

I am facing problem of too many CLOSE_WAIT.
My env is  :

solr 3.4 in Linux RHEL 5.2. I am getting around 1 million request per day
on application server on my production.
Production server is communicating locally with solr server.
I have 5 core setup and for each core I am using seprate instance of
solrServer with following snippet of code.

MultiThreadedHttpConnectionManager cm=new
MultiThreadedHttpConnectionManager();
            cm.getParams().setMaxTotalConnections(100);
            cm.getParams().setDefaultMaxConnectionsPerHost(100);
            cm.closeIdleConnections(0L);
            HttpClient httpClient=new HttpClient(cm);
            server=new CommonsHttpSolrServer(url, httpClient);

At starting my server responding fine but as time progress it start
responding slow and then stop working (within a day). Only solution at that
time is to reset the application server.
What I notice is at the time when server start responding slow that time
CLOSE_WAIT increased. When I reset the application server CLOSE_WAIT become
0. I search and find it is due to CLOSE_WAIT.

Please suggest me how to resolve this CLOSE_WAIT issue.
