That exception code is commonly seen when File I/O operations are done within a Timed Loop. I would make sure that all File I/O operations are done within a regular Loop.
The log can aid in finding the problem but is only very helpful when it is submitted into our log system. When the option to send the Log to NI please do so and then post the Mini Dump ID so that we can take a look and see if it correlates with other logs.
Please first check the File I/O and let us know if you find the problem. If you can not find the problem please recreate it and submit the log when it asks.
