Shutting down Seda

I guess I'm not really sure why this is happening, and would like to understand options for graceful shutdown
of Seda. I realize this is unusual, but Seda is being started in an InitCore method implemented as 2.3 Servlet
in a web application, as an 'init' servlet. When the web service shuts down, we get this exception. Any help
understanding my options is appreciated.
