Samba log spam when network is down

[Reaperzx]

Some months ago I upgraded from Samba3 to Samba 4.6. After that I have discovered, that samba spams into /var/log/messages every few minutes...

My network configuration: In addition to normal home network I have 10G fiber link between my Windows desktop and FreeBSD home server. So when desktop is turned off, then 10G network link is down. And then of course Samba cannot send any packets.

Now the question is how to turn off those useless messages. With Samba3 I did not get such log spam.

I would suggest upgrading to net/samba48 or net/samba410 first. Samba 4.6 is deprecated and this issue may have been resolved already in newer versions.

Samba 4.6 and 4.7 will actually be removed next week.

Upgraded to Samba 4.8, no change. Still getting log spam.

I guess the problem is something changed in Samba 4, compared to Samba 3.
