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