Update about the dovecot-version: both server running now with 2.3.17 -
problem on the only one server still present.

Hi there,
I have setup a replication between two dovecot servers. It seems working:
# doveadm replicator status '*' && doveadm replicator dsync-status &&
doveadm replicator status
username priority fast sync full sync success sync failed

But on the one server, I found this errors repeating and this users
are at the list above marked as failed:
Oct 18 09:41:08 dsync-local(1...@tld.de): Error: Couldn't lock
/srv/mail/mail_storage/tld.de/1/.dovecot-sync.lock:
fcntl(/srv/mail/mail_storage/tld.de/1/.dovecot-sync.lock, write-lock,
F_SETLKW) locking failed: Timed out after 30 seconds (WRITE lock held
by pid 71613)
The directory shows:
# ls -la /srv/mail/mail_storage/celebrate.de/1/ | grep '\.dove'
drwxrwxrwx 5 vpostfix vpostfix 4096 Oct 18 08:55 .dovecot
-rw------- 2 vpostfix vpostfix 0 Oct 18 09:37 .dovecot-sync.lock
-rwxrwxrwx 1 vpostfix vpostfix 912 Mar 20 2023 .dovecot.sieve.log
-rwxrwxrwx 1 vpostfix vpostfix 275 Oct 11 00:00 .dovecot.svbin
So it seems, that there are more processes want accessing same locking
file. But normally this and other files should not exist there:
# ls -la /srv/mail/mail_storage/celebrate.de/fk/ | grep '\.index'
-rw-rw-rw- 1 vpostfix vpostfix 194008 Oct 17 12:26 dovecot.index

In my config, I have set:
mail_location =
maildir:~:VOLATILEDIR=/dev/shm/dovecot/%2.256Nu/%u:INDEX=/opt/dovecot/%2.256Nu/%u:ITERINDEX
But below /dev/shm/dovecot and /opt/dovecot, directories and files are
generated too
Following my config and hoping for some useful hints:
