Hi all,

I have a Jboss WS which handles 50,000 SOAP requests everyday. Almost every 10,000 requests i got an Exception:

ERROR org.jboss.ws.core.jaxws.SOAPFaultHelperJAXWS - SOAP request exception

I know it is an Exception about "Read Time", but , read what??? read request from client or something comes from server? What could it be?

Lots of thanks in advance for any explanation/help
