EntireX Error after Upgrade

I receive this error sometimes when making an EntireX call:
Error : 0020 0208 Return Code 208 0 from Broker Stub.

The application was running on Windows 2003 32 bit EntireX 7.3.3 with no problems and it was upgraded to Windows 2008 64Bit EntireX 8.2.2. All the EntireX calls work on the new setup but sometimes (randomly) I receive the error above. Any ideas as to what is causing this error?

Thanks in advance.

please open a support request with Software AG support for this.
