Warning when running a load test

[Afkham Azeez]

Hi folks,
We are using embedded Tomcat 7.0.14, and when we are running load tests, we
get the following warning from time to time.

WARN {org.apache.tomcat.util.net.JIoEndpoint} -  Incorrect connection count,
multiple socket.close called on the same socket.

What does this mean? What are the implications of this warning?

Thanks
Azeez
