Problem with NOT NULL BLOB field when using ADO AppendChunk.

When I try to use the ADO AppendChunk within a VC++ program and the LONG VAR or BLOB field has a NOT NULL constraint I get a native ORACLE error of 60 (Deadlock, it doesn't make any sense). If I remove the NOT NULL constraint from the BLOB field, everything works just fine. I am using the ORACLE driver.

The question is why? Is this an error in the way ADO is interfacing to ORACLE, a bug in ORACLE itself, or working as designed?
