All of a sudden I found out that my OpenStack server hit a file size limit. I immediately thought it had something to do with glance and my images, but upon inspection I found that a keystone/token.ibd file grew to 32GB!

$ sudo ls -ltrh ./var/lib/mysql/keystone/token.ibd
-rw-rw---- 1 mysql mysql 34G Apr  5 15:48 ./var/lib/mysql/keystone/token.ibd

This looks to be the keystone database. Does anyone know what could have caused it to grow to this size, how I can prevent this, and how I can potentially fix it? I haven't been able to find anyone with such an issue.

Edit: This might be the issue? http://docs.openstack.org/admin-guide...
