ghostscript

Having a problem with Ghostscript processes that don't end. This does not happen often, probably once every 3 weeks we see this issue with 1-3 processes. Running CentOS 6.4 on a VPS from Rackspace. We use PrinceXML to generate PDFs which uses GhostScript to handle fonts.

Here's an image of top: http://i.stack.imgur.com/J9D7D.jpg

As you can see those two processes are using a lot of resources, I haven't killed them yet in hopes someone can help me diagnose. I'm a developer not a server admin so I have a basic knowledge of *nix but no clue on how to fix this.

Installed strace and ran it on each process with the following command: strace -p 20619 -s 80 -o gs.txt

Left it for 5m, gs.txt is empty?

Thanks in advance!
