Cyrus database crashes

Has anyone here experienced the problem with your cyrus mail database going south in MacOS X Server 10.3.x (most notably 10.3.3 although it happened in 10.3.1 too)? What happens is that the db requires a rebuild which is sometimes successful and sometimes not it seems. There are detailed discussions on Apple’s MacOS X Server 10.3 discussion boards, specifically under the “Mail database corrupted” topic and “10.3.2 Mail Server: error on RECONSTRUCT” topic. There is some thought that the problem has to do with the cyrus log rotation and incorrect permissions causing a crash and a corrupted database. This has happened twice to me in the last 3 weeks, once in 10.3.1 and the most recently in 10.3.3. The later time with 10.3.3 I could not recover the db and had to completely rebuild the server from scratch.
