This should help: http://hg.dovecot.org/dovecot-1.1/rev/8cc0eaec7d0f

I've seen this before, but I've really no idea how to reproduce it. Can
you get a gdb backtrace from this? See http://dovecot.org/bugreport.html

Either because of an internal bug or because the mbox file changed
unexpectedly. Possibly due to NFS read cache issues.

This should help: http://hg.dovecot.org/dovecot-1.1/rev/f690d84a9fcb

I'm not sure about this. Can you get gdb backtrace?

This should help: http://hg.dovecot.org/dovecot-1.1/rev/1d8bd4bc3038

What do you use as NFS server? Does it support nano/microsecond
precision in mtimes? Could you post your dovecot -n output? You should
use mail_nfs_storage=yes at least.
