Stuart- Thanks for the pointers. Using the MSU server works.
I'll forward the information to our IT folks.

You will need access to your server's command line, or ask someone who has that access to take a look: Look in /etc/httpd/logs/error_log for lines such as: "/home/httpd/perl/tmp/abert_tccfl_<UNIXTIME>_<NUM>_plot.data" <error>, referer: <URL> where <UNIXTIME> is timestamp (seconds since epoch) e.g., 1408699963 where <NUM> is a numeric ID e.g., 1149728 where <error> is the error message generated by gnuplot where <URL> is the URL of the resource being displayed. The command sent to gnuplot will be in: /home/httpd/perl/tmp/abert_tccfl_<UNIXTIME>_<NUM>_plot.data and if this was a data plot, then the data will be in: /home/httpd/perl/tmp/abert_tccfl_<UNIXTIME>_<NUM>_plot.data.0 Other things to try ... Do you see the same issue when your session is hosted on one of the MSU servers, e.g., log-in via: https://s10.lite.msu.edu/adm/login?domain=tccfl and you display the same resource?
