Afkham Azeez commented on WSAS-194:
-----------------------------------
We think the issue was because when Jetty was used, the TCP connection was
broken while the stream is being read. Therefore the XML read is not valid. We
have eliminated Jetty long time ago, and now use embedded Tomcat, and the
problem does not occur anymore.
> Error occurred in the System Statistics page after the page being refreshed
> several times
