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?
MJ
