Sun Java Application Server Performance with Web Services

We are running a web service on SJAS (Standard Edition). Load testing under 1 or 2 users works alright, but with 5 users making concurrent web service calls it immediately crashes the domain. Has anyone else run into performance issues when using SJAS with Web Services?Are there any configuration parameters we need to setup to handle more than 1 connection?

I'm sure that the application server can handle many concurrent connections, just not sure how to configure and where to look for more information. If anyone is aware of actual numbers for load testing, that would be great information.

Thanks,

Dawson
