This is very odd. Flint currently seems rock solid for everybody using
it apart from you where it seems very flaky. If I could reproduce the
problem, I should be able to pin down what's wrong and fix it, but I
can't from the information you've provided so far.
For example, Gmane uses xapian-compact to merge 2 databases every night,
and even uses the -F option like you do. For a full rebuild (which I
must have done at least 10 times) it merges one database per million
documents, so that's more than 30. Tweakers.net use flint on a large
system and run xapian-compact frequently and they're very happy with
the stability. I know of several other happy flint users (and there
are probably more I don't know of).
I don't understand what's the difference which is causing you these
problems. I suspect if we can work that out this will be fairly easy to
resolve.

If you can run copydatabase on a database, it's in good shape with the
possible exception of the postlist table.
If you want something more specific, quartzcheck is probably a good
starting point. The flint and quartz formats still have quite a bit
in common.
