Hi All,
We recently moved from RHEL6 to RHEL7 and updated dovecot from dovecot-2.2.10-1_14.el6.x86_64 to dovecot-2.2.36-8.el7.x86_64. We use NFS for storing the mail, and 5 servers running at the same time. Before updating dovecot we stopped the service and deleted all dovecot.index* files Now we're experiencing some problems. For example, when deleting an email it is note deleted and appears again duplicated. These are the logs:
Feb 28 08:50:42 server5 dovecot: imap(user@domain): Error: Index path/Maildir/dovecot.index: Lost log for seq=5 offset=228: Missing middle file seq=5 (between 5..4294967295, we have seqs 4): Log is locked transaction log path/Maildir/dovecot.index.log at sync_offset=10328
- newer log can't exist (initial_mapped=1, reason=Index mapped) Feb 28 08:50:42 server5 dovecot: imap(user@domain): Warning: fscking index file path/Maildir/dovecot.index Feb 28 08:50:42 server5 dovecot: imap(user@domain): Error: Failed to map

Usually restarting the email client solves the problem for a while. We've tried deleting the indexes but it happens again some time later.
This is dovecot config:

Can you please help me? Thanks in advance and best regards
