bolt.DB.meta(): invalid meta pages

[LtBasco]

First time syncing... When I open the "Sia-UI" program it works until it attempts to synchronize, then I get the error...

When I attempt to move to the "Wallet" tab I get...

I then press "Start Siad"...

Et cetera.

Possible duplicate of issue #2349.

The listen tcp 127.0.0.1:9980: bind: Only one usage of each socket address (protocol/network address/port) is normally permitted error means something is already listening on port 9980. You probably still have a siad process running.

@lukechampine the panic: bolt.DB.meta invalid meta pages error is showing up a lot lately, you may need to take a look at those.

@tbenz9 Nope, happened several times as first open for the day.

The issue was fixed with a clean re-install and re-download of the .db.

[lukechampine]

This is likely related to https://github.com/coreos/bbolt/pull/58 I'm going to work with the bbolt maintainer to implement a more robust fix, which should hopefully solve multiple bolt issues.

@LtBasco or @lukechampine Would you mind changing the title to be more descriptive of the bug? Make finding duplicates much easier!
