Issue in Serving a WSDL from a node http server and using with SOAP UI

I have a nodejs http server which serves a wsdl file stored in the back end. The wsdl file have mapping to xsds which also i am serving. I have 2 xsds which have a cyclic call to each other.When i use SOAP UI. I am getting a redundant call and SOAP UI is crashing.

I have exposed the same wsdl and xsds in a mule app before and it was working fine.

Any idea what is going wrong ?
