Restore hangs on installing packages

[Stewart]

We have a base config that we restore when installing a new firewall. When I do a config restore it always hangs on twice:

/usr/local/sbin/pkg-static-install -y -f pfSense-pkg-darkstat
and
/usr/local/sbin/pkg-static-install -y -f pfSense-pkg-pfBlockerNG-devel

I'm able to identify them by running ps-aux | grep install and killing the process. This allows the restore to complete. I'm then able to go into the Backup/Restore and tell it to reinstall all packages and that process works fine. How can I see what is going on to resolve the problem?
