Recently we have been getting an error when attempting to generate pdfs. The only change of note has been that our server just upgraded to FreeBSD 10. When the process is run I get a HTTP 500 error. I have looked at the error logs and am unsure that it is showing the error. Listed below is the error that is repeated in the log. This is a Civi (4.7.29) install via wordpress (4.9.4). Any help is appreciated.
