What could be causing Ghostscript rangecheck error?

I know next to nothing about MATLAB. I have three MATLAB modules developed by one of our scientists. Using MATLAB Builder JA, I have created Java libraries and these libraries are at the core of three RESTful services running on Tomcat6 using MCR. All three modules produce a slew of plots which are stored as either JPEG or PNG. All three call the "saveas" function to store the plots. On a non-headless Linux server, either Ubuntu 12.04, RHEL6 or CentOS 6.5, all three run as expected and produce the requested plots. On a headless server, again running either Ubuntu 12.04, RHEL6 or CentOS 6.5, two out of three run fine. The third always crashes and reports the following:

 Error using ghostscript (line 186)

The "saveas" function is called like this:

   saveas(gcf, '/home/someuser/output/data/plot.png');

Does anyone have an idea as to what may be going wrong? Running on a non-headless server is fine for development, but I really need to have this working on a headless server.

Any help would be greatly appreciated. Thanks.
