Symptoms

When you run a Microsoft SQL Server stored procedure that uses Microsoft OLE DB Provider for DB2 v3.0 to call a DB2 stored procedure, SQL Server might crash.

This issue occurs randomly when a Distributed Relational Database Architecture (DRDA) packet exceeds the default size for a DRDA packet.

Note The default size of a DRDA packet is 32 kilobytes (KB).

Resolution

To resolve this issue, install the following cumulative update. This update increases the size of the internal buffers of a DRDA packet.
