Syslog service in pfSense v2.8.1 often stop itself
-
That's a compile time fix, it can't be applied via System Patches.
-
wasn't suggesting a "patch" in the current "pf"sense of a patch
On the other hand it is just a binary file, that could be provided and copied into place.
For those not willing to play with "Alpha" builds the release of 25.07.2 would be a great alternative, rather then having to wait for beta or even final release of 25.11
Maybe the "patch system" should have the ability to deliver a hot fix for certain binaries in the future?
somewhat surprising that since BSD at the core a patch could be created with bsdiff and bspatch both of which are available and actually installed as part of the package.Annoying issues (and not that there are that many, this is one) could likely be fixed by providing this ability to either install a new file or run a binary patch, without having to wait for a full drop of the next version.
(the problem with patching vs copying, is as we have seen in that past, the files where different in the same "release" from one day to the next. Refresh my memory when was that 23.xx, I'd have to look it up)point is when there is a will there is a way..
-
Yes we are looking at options.

@jrey years ago there was a p1 release:

Hello,
I'm experiencing the same problem with a client after updating to 25.07.1
I can also confirm that the problem occurs because we have a remote syslog server under maintenance.
Pf's syslogd should continue to work in this scenario.
I hope a fix is found soon.
Thank you, -
@dennypage Huh. I did not know that.
-
As a workaround you can prevent the syslogd process seeing the connection rejection message from the server by adding firewall walls.
You need to pass the syslog traffic outbound with state set to 'none'. And block the incoming icmp rejection if it's not already blocked.
It then just keeps sending to the server.
-
I have the same problem but with version 25.07.1 of pfsense+ and I am in PCI non-compliance. I think it is not that the remote server is not available for me, it is a bug in the version and it is critical.

if it is not this specifically -- then more information is likely required to offer any suggestions --
same issue with code reference

Yes if you're not seeing 'connection refused logged then it's not the same issue. In which case the more info you can give us the better.

Thanks for the tips

Workaround tested on 25.07.1 and working, thanks @stephenw10

@mcury I will try your workaround.
I have just applied 25.11 dev and can confirm that it does not solve the syslog issue.
-
Hmm, 25.11-dev has the patched syslogd. Are you still seeing the connection refused message? What's the last thing(s) logged?

"Service Watchdog" at the moment, maybe a workaround?
I can answer this myself (we rebooted yesterday our syslog server), service watchdog working:
20:43:00 Service Watchdog detected service syslogd stopped. Restarting syslogd (System Logger Daemon) -
@slu How did you implement this - I have never added anything custom to the watchdog.
-
@tsmalmbe not sure what's exactly your question because the custom, but here are the steps:
- install Service_Watchdog package
- Services / Service Watchdog
- Add New Service
- select syslogd
Done :)
-
@slu Yes exactly I needed this very obvious steps clearly spelled out to me :) Thank you.
-
FWIW, I see the service stop randomly, too, but I just use a second HDD mounted on the system drive for my remote logging, so no remote syslog server that might require FW rules. I'd suggest turning on notifications on Watchdog as well so you can check logs.
-
Do you see any errors logged before it stops? I assume you're using syslog-ng locally for the extra disk?
