Assume that you use Microsoft SQL Server 2012 Integration Services (SSIS 2012) or SSIS 2014. When you run an XML Validation Control Flow task on a large input file, after a period of processing, SSIS may throw an insufficient memory exception as follows:
SSIS package "xxx" starting.
Error: 0xC002F304 at XML Task, XML Task: An error occurred with the following error message: "Insufficient memory to continue the execution of the program."
Error: 0xC002928F at XML Task, XML Task: Property "New Source" has no source Xml text; Xml Text is either invalid, null or empty string.
Task failed: XML Task
Warning: 0x80019002 at Package: SSIS Warning Code DTS_W_MAXIMUMERRORCOUNTREACHED. The Execution method succeeded, but the number of errors raised (2) reached the maximum allowed (1); resulting in failure. This occurs when the number of errors reaches the number specified in MaximumErrorCount. Change the MaximumErrorCount or fix the errors.
SSIS package "xxx" finished: Failure
Note The issue occurs regardless of whether the Validation Details property is set to true or false.
