Hello,

Looks like the store is definitely corrupt if it wasn't shut down
properly. By chance, did you get a crash during the sync? I ask
because I have seen something similar twice in a row now on master
post block 400k+ (the last one being at 441857).

Anytime a crash occurs, there's a chance of store corruption,
especially if you're not flushing writes (config setting).

If you're adventurous, you can try removing the flush_lock file and
try restarting bs, but if there was once corruption, even if it
starts, the corruption persists and may cause future crashes and
further corruption.

The correct way to remedy this is to re-sync from scratch.

Unless you *need* to use master (which is currently unstable), I
recommend using version3, which is production/stable.

-Neill.
