Subject RFE , print that LevelDB is doing a recovery...
Date Sat, 31 Jan 2015 23:53:52 GMT
Right now, after a restart, my AMQ server is at 100% CPU and has been so
for about 10 minutes now.

It should really print that it’s doing recovery and have some sort of
progress indicator ideally.

Here’s the stack trace where it’s been for a long time now...
