Exception occured within the external code called by a Call Library Function Node with DAQmx Start Task.vi I have recieved the error that is shown in the attached document.  Can anyone give me a hint as to what I may need to do to fix this?  It occurs at the same point during the software run every time.  The code is also attached.  The error occurs in the DAQmx Start Task.vi.  the error occurs when the counter reaches approximately 6000 (3000 on the front panel).  I am unsure if this is just a coincidence or actually is linked to the problem.  I appreciate any help that you may be able to provide.

For those that are interested.  It was a memory issue.  I was filling up the available memory as the application ran.  I added an input buffer congigure vi and this corrected the problem.
