Hi I came across this error which happend immedately after a mail delivery to the inbox. Should I look for the problem externally to dovecot (ie. file system, operating system) or within dovecot? I never saw this error before installing 2.2.1, with 2.2.2 I seemed to get even more of them so currently back on 2.2.1
Jun 11 00:00:05 rosalia dovecot: imap(myemail@mydomain): Error: Corrupted transaction log file /var/vmail/mydomain/myemail@mydomain/dovecot.index.log seq 311: file size shrank (1184 < 1304) (sync_offset=1304) Are you using NFS or some other cluster filesystem with multiple servers? If yes, see http://wiki2.dovecot.org/NFS. If not, show doveconf -n and describe the setup more.

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

The log corruptions are continuing, I now have 2.2.4 installed. They always seem to happen in proximty to a mail delivery.
Is there anything that anyone can suggest for how to get a step closer to diagnoising the cause? Is there some debugging I can put on that would be useful?
Thanks John
