Syslog service in pfSense v2.8.1 often stop itself

Yes, that's the bug discussed here. The workaround rules will prevent it. https://redmine.pfsense.org/issues/16362#note-5

@aldomoro Possibly the best use of Service Watchdog. Maybe the only one! :)

Hi,
Same problem here:
"Nov 2 22:00:02 pfsense syslogd: sendto: Connection refused" (system.log)
PfSense CE 2.8.1, remote logging enabled.
Anothers instances 2.8 running OK.
Workaround: whatchdog
Thanks.

Same problem here on 2.8.1

Applying the workaround firewall rules will prevent it seeing the refusals so will not stop.

Hi,
Apparently the rule isn't working because the traffic counters aren't incrementing. There's a "let out anything IPv4 from firewall host itself" rule with higher precedence that seems to be capturing UDP traffic to the remote syslog server, even though the new rule is of the "floating" type.

Yeap, they should increment.
-
This is a VPN server located in the DMZ... It has no LAN interface, only a WAN and IPSEC interface, and the counters are not incrementing despite continuous traffic to the log server.
I might be forgetting something obvious, but I reviewed the settings and tested it more than twice.

In any case, the watchdog isn't the perfect solution, but it did the job.
thanks

Looks like you might have the source port set to 514 instead of the destination.
In your first screenshot it's not shown as an OUT rule also but it looks like you corrected that.

Same ongoing issue, remote syslog enabled, it seems rather random, but mostly when the logging machine is down, which is a linux vm on proxmox host.
