Hi,

For the old storage format (PageStore, version 1.3.x), corrupted databases
are reported from time to time, but unfortunately no reproducible test
cases recently. I'm afraid without those it will not be possible to find
the remaining problems.

For the new storage format (MVstore, version 1.4.x), there are some known
problems that are not yet fixed, or not yet included in a public release
(out of memory, re-ordered writes and power failure). This storage format
is much simpler than the PageStore, so I hope all the problems can be found
and fixed here. But it will still take some time; that's why version 1.4.x
is still beta.

In any case, what I would do is create regular backups from time to time.

Regards,
Thomas
