I've created a java web service, and i'm using Tomcat 5.5 and axis2. I created a client for it and it seems to be working fine. I tried to do a load testing; I'm using WAST(Microsoft Web Application Stress Tool) and the number of concurrent connections was set up for 100 users for 1 hour. When it finished, I noticed a thousands of socket errors. I thought that maybe it was my web service, so I tried using the sample web service that came with axis2, which basically just returns the axis2 version. Same thing, 100 users for 1 hour and again, thousands of socket errors. Could someone tell me what could be causing this and how to fix it?
