Strange error in IDP

[Sukesh Nischal]

Hi

After performing an upgrade of the IDP software to version 2.3.6 (which was working prior) I'm now getting an error in my IdP log as follows? Can anyone tell me how to solve this?  Is it related to my xerces library version?

17:06:13.831 - ERROR - Error occurred while processing request
