Agreed. But it is sporadic (I don't have steps to reproduce, so I 
have nothing to submit to Mantis). And I get reports from users, but 
of course they can't reproduce it either.

I have used one of the early 4 betas (from June 2009). I'll be using 
4.6 with the next release of my app.

>What size of db?

Varies a lot (but much *less* than 2 GB, max is probably 50 MB or so).

Mostly textfields. 128

Varies a lot, from 0 to perhaps 5000 characters.

With user reports I can't always be sure, when I see it myself I can 
be sure there was no crash.
