This is unexpected. Can you please share the contents of your keyring file (keys mangled if you so wish)?

Hi Joao,

I'm working with Kane on this. The keyring file is named ceph-ceph1.mon.keyring, and the contents are:

[mon.]
key = XXXXAFVWAAAAABAAnGnXodW2zSRJBzWuGtXXXX==
caps mon = allow *

If this is reproducible, mind installing the ceph-dbg package (or whatever it is called in your distribution) and get us a more detailed trace? if you manage to get it running under gdb and point me to the right place it would be even more awesome :)

Thanks for your advice to install debuginfo and run with gdb. We've found that wrong leveldb version was installed before, after installing right version everything worked fine.
