Hello,

I am getting the following error on my dovecot LMTP server, upon delivery from my postfix mailserver:

Oct 6 03:31:09 m dovecot[36551]: lmtp: Fatal: Error reading configuration: read(/var/run/dovecot/config) failed: read(size=8192) failed: Interrupted system call - Also failed to read config by executing doveconf: /var/run/dovecot/config is a UNIX socket (path is from CONFIG_FILE environment)

This results in mail being deferred by postfix (different host), and successfully delivered at the next try:

Oct 6 03:31:10 mailer postfix/lmtp[44835]: 46F0BA329: to=d@l.ynx.fr, orig_to=<root>, relay=192.168.1.101[192.168.1.101]:24, delay=17, delays=0.2/0.01/16/0, dsn=4.4.2, status=deferred (lost connection with 192.168.1.101[192.168.1.101] while receiving the initial server greeting)

Any idea where it comes from?

I am running dovecot 2.3.21.1 (d492236fa0) on FreeBSD 14.1-RELEASE-p5.

Here is my configuration:

# 2.3.21.1 (d492236fa0): /usr/local/etc/dovecot/dovecot.conf # Pigeonhole version 0.5.21.1 (49005e73) # OS: FreeBSD 14.1-RELEASE-p3 amd64 # Hostname: m.ynx.fr
