Failed to map transaction log path - Stale file handle

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 at 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 
- newer log can't exist (initial_mapped=1, reason=Index mapped)
Feb 28 08:50:42 server5 dovecot: imap(user at domain): Warning: fscking 
index file path/Maildir/dovecot.index
Feb 28 08:50:42 server5 dovecot: imap(user at domain): Error: Failed to map 
transaction log path/Maildir/dovecot.index.log at sync_offset=10328

Feb 28 08:50:42 server5 dovecot: imap(user at 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): Requested 
newer log than exists - still after NFS flush: Log inode is unchanged 
(initial_mapped=1, reason=Index mapped)
Feb 28 08:50:45 server5 dovecot: imap(user at domain): Error: Failed to map 
transaction log path/Maildir/dovecot.index.log at sync_offset=10328 
after locking: pread() failed: Stale file handle
Feb 28 08:50:45 server5 dovecot: imap(user at domain): Error: Failed to map 
view for path/Maildir/dovecot.index: Missing middle file seq=5 (between 
5..5, we have seqs 4): Requested newer log than exists - still after NFS 
flush: Log inode is unchanged

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?

Hi!

Are you ensuring that the same user is not concurrently being accessed by
multiple backends. All mail sessions for a user, including mail delivery.

Are you using NFSv3 or NFSv4?
