The darshan-job-summary.pl as installed on eureka fails to generate a pdf with log files containing lots (93,000+) records.

you can sort of see for yourself (except the error reporting is horrible here: i'll open a new bug for that):

darshan-job-summary.pl /intrepid-fs0/logs/darshan/2010/10/1/mmin_nekcem_id314635_10-1-13849_4.darshan.gz

after 3 minutes there will be an error about unable to move summary.pdf

I had to hack up the perl script to keep the temp dir handy and run pdflatex myself. the error from pdflatex (once it is no longer diverted to the output file) is the fairly terse

Overfull \hbox (44.47777pt too wide) in paragraph at lines 95--96
