[Dovecot] file descriptor errors

Hi,

I use dovecot 2.2.9 on Gentoo Linux and I get lots of these erors in my log
file:

Dec  4 08:53:37 mx dovecot: auth: Error: close failed in file object destructor:
Dec  4 08:53:37 mx dovecot: auth: Error: IOError: [Errno 9] Bad file descriptor

What could cause these error messages?

My mailboxes are stored on an ext4 filesystem:
/dev/vdb1 on /srv/mail type ext4 (rw,noatime)
