solrj and CLOSE_WAIT's

[Ian Holsman]

Hi guys.

I'm running a little upload project that uploads documents into a solr 
index. there is also a 2nd thread that runs a deleteby query and a 
optimize every once and a while.

in an effort to reduce the probably of things being held onto I've made 
everything local, but it is still collecting CLOSE_WAITs and FIN_WAIT2's 
on the server side until it eventually runs out of file handles in a day 
or two.

the following are the code snippets being used to call solr.

   protected void doArchiveSolr() throws IOException, SolrServerException {
       Calendar rightNow = Calendar.getInstance();
       rightNow.add(Calendar.DATE, 31 * -1);
       DateFormat f = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
       java.util.Date d = rightNow.getTime();

       String s = "publish_date:[1976-03-06T23:59:59.999Z/YEAR TO " + 
f.format(d) + "]";
       logger.info("Archiver:" + s);
       CommonsHttpSolrServer solrServer;
       solrServer = new CommonsHttpSolrServer(solrURL);
       solrServer.deleteByQuery(s);
       solrServer.commit();
   }

and this runs every X minutes.
it also has other local parts like
{
  CommonsHttpSolrServer solrServer;
  solrServer = new CommonsHttpSolrServer(solrURL);
  solrServer.optimize();
}


and
{
                       CommonsHttpSolrServer solrServer;
                       UpdateResponse r;

                       solrServer = new CommonsHttpSolrServer(solrUrl);
                       solrServer.setSoTimeout(120000);  // socket read 
timeout  2minutes
                       solrServer.setConnectionTimeout(100);
                       solrServer.setDefaultMaxConnectionsPerHost(100);
                       solrServer.setMaxTotalConnections(100);
                       solrServer.setFollowRedirects(false);  // 
defaults to false
                       solrServer.setAllowCompression(false);

                       r = solrServer.add(docs);

                       r = solrServer.commit();
                       docs.clear();

}
