Multisource universe issue with Teradata

Hi,

I am creating a Multisource universe connected to SQL server and Teradata. I was able to create WebI report by adding objects from both data source the report is running at some instance and later it is not running.

The report is running properly when the objects for SQL sever or Teradata alone is pulled in reports. But give errors when pulling objects from both datasource.

If we restart the Adaptive Processing Server and SIA  the report is getting executed successfully and again after some run we are getting the following errors,

1. CORBA error while communicating with the SL service: WIS 00000

2. processDP session failed

Any input will be helpful.

Thanks,
