huge increase in storage activity afther dovecot upgrade

Hi,
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:

Nov 12 09:48:16 mail dovecot: imap(...): Error: Corrupted index cache file
/.../dovecot.index.cache: invalid record size
Nov 12 09:48:16 mail dovecot: imap(...): Error:
unlink(/.../dovecot.index.cache) failed: No such file or directory (in
mail-cache.c:29)
Nov 12 09:48:16 mail dovecot: imap(...): Error: Corrupted index cache file
/.../dovecot.index.cache: invalid record size
Nov 12 09:48:16 mail dovecot: imap(...): Error: Broken file
/.../dovecot-uidlist line 8: Invalid data:

Is this normal ?
Will the activity wind down ?
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 ?

Thank you !

Here's my configuration:

huge increase in storage activity afther dovecot upgrade

It should eventually wind down once all the problems are fixed. Of
course if it does not happen, you can always run force-resync for the
problem users.

huge increase in storage activity afther dovecot upgrade

Thank you !
I was little concerned that the following settings are not in line with the
new version:

mail_nfs_index = yes
mail_nfs_storage = yes
mail_fsync = always
mailbox_list_index = yes
maildir_stat_dirs = yes
mmap_disable = yes
