I use Dovecot 2.0.12 on FreeBSD 8.2-RELEASE and didn't see any index
corruption in log so far. Admittedly the setup is relatively new, and
have been running for only 63 days now, but my understanding is that I
shouldn't be that lucky. Also, FreeNAS uses both mmap and sendfile and
we didn't see data corruption either nor see any reports about that.
Note that my instance is running a heavily modified version (with some
driver updates, ZFSv28, etc) though, the latest 8-STABLE have most of
the ZFS changes I had in my own tree but I don't think these changes are
related to data corruption.
If, however, you could reproduce a data corruption on your installation
on a recent unmodified FreeBSD 8.2-RELEASE system, please do let me know
or post your complain on freebsd-stable at freebsd.org, as that would be a
pretty serious problem and we will get it fixed as soon as possible.
