userland calling deprecated sysctl, please rebuild world

Right but a firewall/router is not a host. Almost all traffic passes through it and those TCP tunables apply to traffic terminated on the system.
Why have you added them? Were you seeing a problem? Did it help?
One of those is causing the error you are seeing. So if you want to not see it you need to stop applying that tunable.

You still have not shown us the log containing this error for context so we can only guess what is calling it. You must have something custom on that box.
To confirm you have removed the custom sysctls from Sys > Adv > System tunables?
sysctl.conf will just get rebuilt at boot.Steve

Ok, so it occurs multiple times and not just at boot? Some minutes apart?
Does it log that continually?
That's not a sysctl that is applied at boot then. You have something else on that system actively setting something that's no longer valid. Do you have something else running there? Some other custom script or manually added package?

Good day!
After a long search for the error found the following.
The problem appears when enable an additional parameter in the Zabbix agent settingsEnableRemoteCommands=1

Nice find.
