Connection or SQL Sentence Error (DA0005)

Some of our users experience this problem when running BO reports. The report will run fine 1-2 times, then the 3rd time the report stalls and we get the following message in a pop-up window: Connection or SQL Sentence Error (DA0005) Detail: Exception: CS, unexpected behavior.

The reports run fine on the full client BO load, but error out on the ZABO install. We run BO 6.5 SP4.

I am just trying to get a feel if this is a BO problem or related to a database (we run Oracle & Teradata) or possibly a network issue. It happens to ZABO users on-site as well as remote connected users.

Would anyone know what the error code means?

Thanks, Christine
