Repeated errors from the Ole DB Provider for DB2 eventually cause a .NET System exception or a Win32 access violation (C0000005) (821988)
The information in this article applies to:
- Microsoft Host Integration Server 2000
- Microsoft Host Integration Server 2000 SP1
SYMPTOMSWhen you use the Ole DB Provider for DB2 (DB2OLEDB) from a
.NET Framework application that is using the Managed Provider for Ole DB, a
System exception is thrown after repeated errors are returned from the DB2OLEDB
Provider. Depending on the type of .NET application, this exception
may be one of the following and typically occurs after 40 to 50 errors have
been generated:
- System.ExcecutionEngineException
- System.StackOverflowException
- another type of System exception
CAUSEThe DB2OLEDB provider is incorrectly returning a pointer to
an existing error string, instead of allocating a new error string in its
implementation of the Ole DB GetErrorDescription function.
After a certain number of errors, the
original string is freed from memory. As a result, when the Managed Provider
for Ole DB tries to free the error string that is returned by DB2OLEDB, an
access violation occurs because the string has already been
freed.RESOLUTIONService pack information To resolve this problem,
