This is ... useless. Since metadata is broken, the only way to get
correct DB is to pump data from broken DB to a new, clean DB.

Al that you said about DB defects, can be caused by
- bad RAM
- updating metadata while working with data. 2.5 is more stable in
that situations, but I think there is still some problems can hide.
Do your application allow to change metadata? How often?
