[ZODB-Dev] Problem with RelStorage zodbpack

[Erik Dahl]

I was running a pack and canceled so that I could reboot my box.  After it came back up I tried to restart the pack and got this:

I'm in process of running mysqlcheck against the database and I have the application off line.  I've looked at the code but I'm not 100% what it's trying to do.  Thoughts?  Is my database hosed? or just my packing process.
