Hi We used Solr4.6 for search and there was a exception occured randomly. The exception message in application(use SolrJ) was :

occured because of the solrServer has too many connections at 1 second, But we used Jmeter to simulate a very heavy load on the solrSever,and the similar Excepion was not hanppened. We used SolrJ in the application,and the SolrServer class was HttpSolrServer class with the default HttpClient. The solr was run on Tomcat,and the Tomcat config was the default config. And now we still receive this Exception a few times a day. Any ideas on what the root cause of this issue may be and how we can remediate it. Thanks.
