net_connect_unix(/var/run/dovecot/stats-writer) failed: Permission denied
Hi,
We are getting very occasional messags from dovecot:
net_connect_unix(/var/run/dovecot/stats-writer) failed: Permission denied
Over the last week, the message appeared five times. (on a mail server with over 100 users, to that's basically almost never)
doveconf -n below
2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf
Pigeonhole version 0.5.4 ()
OS: Linux 4.19.0-10-amd64 x86_64 Debian 10.6 xfs
snip...
service stats { unix_listener stats-reader { group = vmail mode = 0660 user = vmail } unix_listener stats-writer { group = vmail mode = 0660 user = vmail } }
and the on-disk permissions are:
root@dovecot:~# ls -l /var/run/dovecot/*stat* srw------- 1 root root 0 Oct 6 00:25 /var/run/dovecot/old-stats prw------- 1 root root 0 Oct 6 00:25 /var/run/dovecot/old-stats-mail prw------- 1 root root 0 Oct 6 00:25 /var/run/dovecot/old-stats-user srw-rw---- 1 vmail vmail 0 Oct 6 00:25 /var/run/dovecot/stats-reader srw-rw---- 1 vmail vmail 0 Oct 6 00:25 /var/run/dovecot/stats-writer
We're not sure what makes the Permission denied error happen...
Anyone with an idea?

Hi,
Nobody?
It happens so rarely, and the system appears to be running fine otherwise, should I just ignore it?
Still makes me wonder way it would happen at all..?

Hi!
You can ignore it, or you can change the socket permissions to 0666.
service stats { unix_listener stats-writer { mode = 0666 } }

Hi, I'm seeing the same, but I think it's every time the lda is called to deliver mail to a mailbox. Postfix runs it as vmail:vmail.
My socket is owned by root:dovecot (on Debian buster).
Should I add vmail to the dovecot group to enable it to write? Or is changing the socket to 0666 safer?
I'm also a little confused, because according to https://doc.dovecot.org/configuration_manual/stats/ no statistics are logged by default, and I have no mentions of 'metric' anywhere in my config, so why is the write even attempted? (dovecot 2.3.4)
Cheers, Richard
