When booting an ami if confd is not up when the migrate.sh script is triggered the database tables never get created. This leads to the site being unable to store the pastebins.

Not sure what is causing, but I've just seen 2 different dpaste instances
come up with this problem, apache isn't running on them.

Looking at /var/log/apache/error_log shows me:

Core dump isnt' very helpful

Feels to me like the apachectl graceful in confd might be the culprit

Other theory, the migrate script doesn't restart apache when it's done and it was already running, maybe
dpaste doesn't like it's settings changing from under it

So it would seem to me that mod_wsgi experiences something not fun and crashes

Oh, and from all this, I also notice we use the worker MPM by default instead of the much safer/simpler
prefork MPM
