Is there anything else I could do? I could try to recompile php with -g so we can see the n/a symbols?

My setup is quite standard: nginx + PHP-FPM for a Wordpress site. After running smoothly for a couple of days, the processes will start segfaulting. I'm running Archlinux's php-7.0.3-1 whose configuration can be seen at https://projects.archlinux.org/svntogit/packages.git/tree/trunk?h=packages/php I have not yet been able to reliably reproduce the issue. All I know is that it happens after a few days and that a restart fixes it.
