Hi Team,
We have .Net application consuming tomcat solr3.5 services and deployed on Windows Server 2012. Its is 64 bit machine with 32 GB RAM and Tomcat veriosn is 6 and is installed at :"C:\Program Files (x86)\Apache Software Foundation\Tomcat 6.0". During the peak load, the solr sevice stops/unresponsive and it is happening very frequently. We didnt fount any erro logs in windows event viewer but in tomcat logs we got the following exception : Aug 06, 2014 10:51:18 AM org.apache.solr.common.SolrException log SEVERE: ClientAbortException:
