`Incorrect key file for table 'pro_accounts_auto_signin'; try to repair it` during `bin/run.sh`

I've been generally following [this guide for installing `hackpad` on CentOS](https://www.rosehosting.com/blog/how-to-install-hackpad-on-a-centos-7-vps/) to install it on my Fedora box. Everything seems fine except for getting a `Incorrect key file for table 'pro_accounts_auto_signin'; try to repair it` error during `bin/run.sh`.

[Everything I've read](http://planet.mysql.com/entry/?id=32629) seems to indicate this is either a probably with not enough disk space or with a corrupted table, but I have both plenty of free space and trying to repair that table doesn't work.

Thoughts?
