nmbd fails to start with locking error on ctdb/samba upgrade

[Steve French]

Anyone run into something like this (in upgrading to 4.5-latest
ctdb/samba/nmbd)?

nmbd fails to start with "invalid argument" on g_lock_tdb.2

ctdb log info:

The lockfile exists and is rather large at a size of 5206016:
