OracleException Deserialization

[dave v]

I thought I read in an earlier post that there are known issues with
deserialization in the System.Data.OracleClient.dll. Can anyone expand on
that or give a workaround?

I'm calling a custom database component that uses ODP.NET from a BizTalk
2004 map. When this component throws a
System.Data.OracleClient.OracleException, I get this in the EventLog:
Failed while creating a NUSTestHarness.NUSTest service.
Exception type: ServiceCreationException

Additional error information:

Additional error information:
(The error actually happens when I resume a suspended resumable instance of
an orchestration that calls a child orchestration which makes the Oracle call
and catches the exception.)

Any Ideas?
