slapcat will fail the same way here. Whatever you last did to change either the 
software or the DB, you'll have to undo yourself or simply start over. This 
error indicates that an item being requested from the DB is larger than 
expected. Since the item in question is a fixed size, as I said before, this 
should never happen.

Another possibility is that you created the DB on a 64-bit machine and are now 
trying to read it with 32-bit code, since that would also affect the size of 
the item in question.
