<div>Hi,</div>
<div>we upgraded our servers from version 2.2.13 to
2.2.27. After the upgrade we notice a 10x increase in
traffic with the nfs storage an errors like this in the
logfile:</div>

<div> Nov 12 09:48:16 mail dovecot: imap(...): Error:
Corrupted index cache file /.../dovecot.index.cache:

Nov 12 09:48:16 mail dovecot: imap(...): Error: Broken
file /.../dovecot-uidlist line 8: Invalid data: <br>
<br>
</div>
<div>Is this normal ? <br>
</div>
<div>Will the activity wind down ?</div>
<div>Can we do something, like deleting the old
dovecot.index* or dovecot-uidlist files from maildirs,
or doing an doveadm force-refresh for all inboxes ?</div>
<div><br>

<div>Thank you !</div>
