EndPoint Agent issue with large files

We are having an issue that involves PCs with the agent installed. When a user tries to copy a file that is over 30mb, they cannot. There is no error message, the file will not copy. Smaller files/folders can be copied, large files/folders cannot. The end user states that the computer "crashes" but I do not have any detail on what that means yet. We have set the agent "Detection.MAX_FILTER_FILE_SIZE.int" set to 31457280 Bytes (30mb).
