Tested on system (see above) with ~ 2GB memory. A simple way to reproduce, is to use the following procedure to attempt to display a font: 1) Invoke ghostscript on 'prfont.ps' $ gs /usr/share/ghostscript/9.10/lib/prfont.ps GPL Ghostscript 9.10 (2013-08-30) Copyright (C) 2013 Artifex Software, Inc. All rights reserved. This software comes with NO WARRANTY: see the file PUBLIC for details. Loading NimbusRomNo9L-Regu font from /usr/share/fonts/type1/gsfonts/n021003l.pfb... 3896292 2355421 3853784 2540955 1 done. GS> 2) At Ghostscript prompt, specify a random fontname - which we know does not exist - to 'DoFont': GS>/Somefont DoFont Can't find (or can't open) font file /usr/share/ghostscript/9.10/Resource/Font/Somefont. Can't find (or can't open) font file Somefont. Querying operating system for font files... Result: memory usage maxes out, system swaps and hangs. I expected Ghostscript to conclude the font search (without exhausating system resources!) and to report failure to locate the specified font. This problem always occurs, and affects any other program which invokes ghostscript and triggers a font search.
