Cause

The smb (SAMBA) service, which is disabled by default, has been enabled.






Resolution

1 - Check if the smb service is running:
root@avamar:~/#: service smb status
smbd (pid 2260 2256) is running...
nmbd (pid 2261) is running...

2 - If it is running, manually stop it:
root@avamar:~/#: service smb stop
Shutting down SMB services:                                [  OK  ]
Shutting down NMB services:                                [  OK  ]

3 - Ensure the service will not be started during the upcoming reboots, by disabling it for all the O.S. run levels:
root@avamar:~/#: chkconfig --level 2345 smb off
root@avamar:~/#:

4 - Verify that service is now OFF for all O.S. run levels:
root@avamar:~/#: chkconfig --list |grep smb
smb             0:off   1:off   2:off   3:off   4:off   5:off   6:off

5 - Acknowledge all existent events:
admin@avamar:~/>: mccli event ack --all
0,23000,CLI command completed successfully.
Attribute    Value
------------ -----
events-acked 81

6 - Allow several hours then check again to make sure the unwanted events are gone:
root@avamar:~/#: mccli event show --unack;date
0,23000,CLI command completed successfully.
