(SOLVED) System log growing too large

[Steviewunda]

Hi - after a few days Fix Common Problems states that the system log has grown too large, and the system becomes less responsive - until I restart the unRaid server. Any help appreciated - diagnostics log attached

Do winbindd and nmbd mean anything to you? Likely something you installed, or it's used by plugin or something.

Thanks Johnnie - no I don't know what they relate to. The only dockers running are duckdns and openvpn-as. I have just shut them down to see if those log entries are are related to either of them. I have also just removed Dynamix Local Master for troubleshooting purposes

Here are my SMB extras, if they could be relevant:

[rootshare]
path = /mnt/user
comment =
browseable = yes
# Public
public = yes
writeable = yes
vfs objects =
[global]
domain master = yes
preferred master = yes
os level = 255
log level = 3
logging = syslog

Typically NMBD is for resolving NETBIOS system names. It runs as part of SAMBA.

Typically WINBINDD is used for resolving users and groups for Windows NT servers. It runs as part of SAMBA.

Thanks Brit - I'm wondering if I should remove the  lines in the SMB extras (see above) pertaining to logging? Or remove the whole [global] section?

[Steviewunda]

I seem to have resolved this by removing the [global] section of the SMB extras (see above). Thanks very much to those who responded

These were the culprits, they increase Samba's log level and output everything to the syslog.
