[Samba] smbd's using up 100% of all cpu's and load avg slowly going up

Mon Dec 29 07:58:59 MST 2014

Hi,

Yes, I already thought about it.

I have the sernet repo installed.. Is possible to yum update and jump
from 4.1.6 to 4.1.14 directly, without problems or should I follow some
kind of procedure to avoid future problems?

Regards,
Bruno Andrade.
