CAUSE:
There is a bug in the OpenLink ODBC driver that shows up under heavy load. Extensive testing has been done of the ESQL/C code during the researching of this problem and all testing shows that the ESQL/C code is performing properly.
FIX:
Contact OpenLink Software and request that they help debug their driver
