DB2 CONNECT / DB2CONNCT / A10 - DB2

ADO.NET application is getting AccessViolationException when 
performing a batch insert of large binary values in a table that 
contains a BLOB column. The batch insert is performed by setting 
the "ArrayBindCount" property on the DB2Command instance. 
 
The application throw AccessVoilationException when inserting 
200 rows of binary data in a table using array insert. One of 
the column in this table is a BLOB and size of largest BLOB data 
in binary file is 1417522 byte. So, the size of application 
array to hold this 200 rows of data is 1417522 x 200 > 2GB. The 
dot.net driver crashes while accessing the row number 146 of 
such big array with access violation exception. The memory 
address of 146th row is going beyond 2GB and hence it 
application buffer pointer gets some invalid address. 
 
Using windbg too, got below stack trace for this issue:
