Managed to capture and strace a snippet

|sendto(40<socket:[11473780]>, "<22>Aug 19 05:38:37 dovecot: imap-login: Login: user=<matt.bryant@XXXXXX>, method=PLAIN, rip=127.0.0.1, lip=127.0.0.1, mpid=30681, secured, session=<2b5XajStxtp/AAAB>", 183, MSG_NOSIGNAL, NULL, 0) = -1 ECONNREFUSED (Connection refused) > No DWARF information found close(40<socket:[11473780]>) = 0 > No DWARF information found socket(AF_UNIX, SOCK_DGRAM|SOCK_CLOEXEC, 0) = 40<socket:[11479193]> > No DWARF information found connect(40<socket:[11479193]>, {sa_family=AF_UNIX, sun_path="/dev/log"}, 110) = -1 ECONNREFUSED (Connection refused) > No DWARF information found close(40<socket:[11479193]>) = 0|

and the usual connection

|u_dgr UNCONN 0 0 * 11469151 * 11469130 users:(("log",pid=28694,fd=38))| |seems to just drop out of existance, the above connection on 2.2 though does reconnect ... |

Has anyone else experienced this issue ?? Not sure if dovecot or centos issue tbh .... ? Anyone have any ideas ???

All,

Running dovecot 2.3.10 on a CentOS 7.x and logging via syslog seems to stop when i restart rsyslog process. Reload doesnt get it working again only a dovecot restart. Tested this with dovecot 2.2.36 and this did not exhibit the same behaviour.

systemctl restart dovecot rsyslog ----- this gets a working state

systemctl restart rsyslog ------------- this restarts syslog other processes like exim continue to log but dovecot stops

systemctl reload dovecot -------------- this has no impact logging still does not work

systemctl restart dovecot ------------- this fixes the issue.

Are there any changes to the log process between 2.2 and 2.3 that might explain this ?
