    Do you know how many files this application is creating? <br>
    <br>
    By default, Darshan should stop tracking new file records on a
    specific process after either tracking more than 1,024 files for a
    given module or if it has exhausted all of its allocated memory.
    This is to keep its memory footprint bounded. The warning message
    you get from darshan-job-summary seems to imply this is what's going
    on, but if your application isn't opening that many files, maybe
    something else is wrong?<br>
    <br>
    Thanks,<br>
