thanks for your response. There is no NFS involved. The file system
seems to  be reiserfs (as reported by df -T) thogh I wonder why
fsck reports it would use fsck.ext2 (which I did not run).

It is a single server vpn container hosting a few sites and
low volume mail service. The operating system is centos 6.4

The setup is with postfix, amavisd and dovecot using sieve. Dovecot and
sieve are built from source

Clients are roundcube and usual mail clients mainly thunderbird.

I cannot link the errors to anything specific, except that they started
happening 5 minutes after upgrade to 2.2.1 from 2.1.5. The error happens on
multiple mailboxes. I never saw the error prior to that, looking at logs
back to
version 2.1.7.

Below is the dovecot -n output

Thanks
John
