Serge, Thanks for responding. Connectors and workers.properties given below. Please note that there is a firewall between server running Apache and the server running Tomcat. All the required ports are open...since the connection does go thru 3 out of 5 times. I found some documentation about adding socket_keepalive=True, and have added it. I'm still testing and don't know if that helped or not. I'd appreciate any thoughts or ideas. Thanks Murali -------------------------------------------------------------- worker.properties # #------ DEFAULT ajp13 WORKER DEFINITION ------------------------------ #--------------------------------------------------------------------- # # # Defining a worker named ajp13 and of type ajp13 # Note that the name and the type do not have to match. # worker.ajp13.port=8009 worker.ajp13.host=localhost worker.ajp13.type=ajp13 # # Specifies the load balance factor when used with # a load balancing worker. # Note: # ----> lbfactor must be > 0 # ----> Low lbfactor means less work done by the worker. worker.ajp13.lbfactor=1 # # Specify the size of the open connection cache. #worker.ajp13.cachesize # application specific worker.ProspectService.type=ajp13 worker.ProspectService.port=8009 worker.ProspectService.host=xxx worker.ProspectService.cachesize=5 # mdurbh, to fix problem with intermittent connection failure worker.ProspectService.socket_keepalive=True <!-- ==================== Connectors from tomcat's server.xml==================== --> <!-- Normal HTTP --> <Connector className="org.apache.tomcat.service.PoolTcpConnector"> <Parameter name="handler" value="org.apache.tomcat.service.http.HttpConnectionHandler"/> <Parameter name="port" value="8080"/> </Connector> <!-- Uncomment this for SSL support.
