I think:
Lock table is out of available locks
Is the key to this problem.  Research on sleepycat for a way to
increase the size of the lock table, and I think you'll be in
business.  Probably something along the lines of set_lk_max_locks
(although your database might already be corrupted)

I suspect ldbm is letting you add it because it doesn't do as much
locking/checking/transactionalstuff as bdb, but is unable to actually
work with an entry of this size.  ldbm is being dropped, so I wouldn't
recommend pursuing it.
