It looks like a legitimate log file to me. `darshan-job-parser`, which<br>
simply dumps the counters and such to stdout, gives me a reasonable<br>
looking log file. here's the header:<br>
<br>

And a <a href="http://darshan-job-summary.pl" rel="noreferrer" target="_blank">darshan-job-summary.pl</a> that I built back in August 2020 generates<br>
a pdf for me in a few seconds. I've attached it for you but really we<br>
should figure out what's going on in your environment<br>
