Facing Java Socket Exception Error
We are facing strange error in our environment.
Work flow:
SAP->Connector->Hardware LoadBalancer->Tomcatservers
RFC call will happen to Connector. Connector converts the RFC call to SOAP. Connector configuration has a URL like http://xyz.com/bc/yz.
xyz - is Hardware load balancer URL. That means xyz is loadbalanced URL for tomcat1:8095,tomcat2:8095&tomcat3:8095.
This configuration is works fine in regular scenarios. But during the peak load times we observed that following error message in Connector logs.
2015-10-06 15:20:17,223 [JCoServerThread-10] ERROR com.vertexinc.sic.webservice.AxisWebServiceClient - (Server.userException) java.net.SocketException: Connection reset 2015-10-06 15:20:17,246 [JCoServerThread-10] ERROR com.vertexinc.sic.webservice.AxisWebServiceClient - Server error 2015-10-06 15:20:17,246 [JCoServerThread-10] ERROR com.vertexinc.sic.webservice.AxisWebServiceClient - The Web Service is not in a valid state. Details: java.net.SocketException: Connection reset
This error means the tomcat server closes the connection abruptly. Is it a resource problem at tomcat server end?

You will need to do some packet captures to determine if your tomcat server is sending the reset or if the F5 is sending the reset. Also, have you checked the F5 logs during the same periods?
