[Dovecot] syncing problems Dovecot 2.2.13

[Götz Reinicke - IT Koordinator]

Hi,

we still migrate a couple of users from mbox to maildir.

Most of them are fine without any problem.

Some crash and dont get all mails synced.

first I sync backup the mbox to a maildir-NEW, than copy mbox to a new
name, mv maildir-NEW to maildir.

Now some problematic mailusers miss some mails from the old mbox, so I
start a dsync mirror and BAM crash.

e.g.:

dsync(s108019): Panic: file mbox-lock.c: line 799 (mbox_lock): assertion
failed: (lock_type == F_RDLCK || mbox->mbox_lock_type != F_RDLCK)

ANY help and suggestion is very welcome on how to procede.
