Problem with task not writing to file

I have a problem where the file writing from a analog reading task will eventually stop working.  The acquisition will work normally but after a period of time (tens of seconds to tens of minutes) it will stop writing files.

The mode of operation is to continuously acquire and periodically switch to a new file.

The key functions are 'readTaskConfigure()' and 'AnalogInCallback()'.  The 'ShowWaveforms' flag is set to false.

I suspect the problem is with resource usage.  Any suggestions on how to make this more efficient would be greatly appreciated.

Thanks,
