syslog logging + 2.3.10 + centos 7

[Matt Bryant]

Managed to capture and strace a snippet

|sendto(40<socket:[11473780]>, "<22>Aug 19 05:38:37 dovecot: imap-login: 
Login: user=<matt.bryant at 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 ???
