faultstring xml:lang="en">a non-numeric character was found where a numeric was expected

Hi,

I am new to SoapUI.

I am testing a wsdl and getting this error.

<env:Envelope xmlns:env="http://schemas.xmlsoap.org/soap/envelope/"><env:Header/><env:Body><env:Fault xmlns:ns0="http://schemas.xmlsoap.org/soap/envelope/"><faultcode>ns0erver</faultcode><faultstring xml:lang="en">a non-numeric character was found where a numeric was expected
ORA-06512 </faultstring></env:Fault></env:Body></env:Envelope>

Can I get some help diagnosing the error?

Thanks!
