> If there is an XML error in the incomming SOAP message, the SOAP builder seem to keep
on reading the stream, without returning an error. This causes the server to hang.
> On XML errors in the SOAP message, the SOAP module must be returning a meaningful error
back and exit the reading loop.
> Here is the gdb trace to help solve the problems.
> Program received signal SIGINT, Interrupt.
