GLOBAL transactions - OCI_TRANS_TIGHT - ORA-00161

I have an application that needs to perform multiple concurrent transactions. To accomplish this I'm trying to use Oracle's Global Transactions. However, I'm having a problem with the OCITransStart() function.

I'm trying to establish multiple branches to operate in a single session and I can't figure out why my call to "(OCITransStart(phService, phErr, 0, OCI_TRANS_TIGHT)" is generating an error message. I'm getting error code 161, with the error message "ORA-00161: transaction branch length 536871073 is illegal (maximum allowed 64)." You can see the context of this call in the code segment below.

I'm under a very tight time constraint and I'd appreciate ANY suggestions that you may have.
