[Samba] Unable to setup messaging listener

[Rafael Domiciano]

Hello people,

Today I noticed that there's a lot of this messages in the 
/var/log/messages:

Jun  9 13:23:00 bcd samba[14033]: [2016/06/09 13:23:00.772684,  0]

My first reaction was to check disk, but there still 5G free:

[root at bcd ~]# df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda3        14G  5,7G  7,1G  45% /
tmpfs           1,9G     0  1,9G   0% /dev/shm
/dev/sda1       190M   47M  134M  26% /boot


Even with this "error" samba is working fine.

My question is: Is safe to ignore it, or I have a real problem?
