dovecot - Dec 2021 - /var/run/dovecot/stats-writer) failed: No such file or directory

Good day Guys

I am getting this error message in the logs.

dovecot: imap-login: Error: 
net_connect_unix(/var/run/dovecot/stats-writer) failed: No such file or 
directory

Running Debian Buster.

With a bit of googling, I tried the suggestions of:
https://forum.iredmail.org/post67042.html#p67042
https://git.ispconfig.org/ispconfig/ispconfig3/-/issues/5343

But still this problem is? persisting.

Here is the config.
~ # cat /etc/dovecot/conf.d/20-dovecot-stats.conf
service stats {
 ??? unix_listener stats-writer {
 ??????? user = dovecot
 ??????? group = mail
 ??????? mode = 0660
 ??? }
}

~ # ls -la /var/run/dovecot/stats-writer
srw-rw---- 1 dovecot mail 0 Nov 21 17:00 /var/run/dovecot/stats-writer

Could anyone please shed an idea or tip of where more too can I look.

Many thanks
Regards
Brent Clark

Those suggested fixes you found have to do with permissions, but in your case
the error is file not found. I would go that direction in trouble shooting. Off
the top of my head two things that could hide files from processes are SELINUX
and CHROOT. (https://wiki.dovecot.org/Chrooting) But no idea if either of those
have to do with your issue.

Hi!

Can you try if adding

service stats {
  unix_listener login/stats-writer {
    user = $default_login_user
    mode = 0600
  }
}

fixes this?

This is default in stats service, I just wonder if there is a version where it
was not yet default...
