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

Hi again,

Sorry, I forgot to include the fd used...

13 -> /var/lib/samba/private/sam.ldb.d/DC=EXAMPLE,DC=COM.ldb
16 -> /var/lib/samba/private/sam.ldb.d/metadata.tdb

the others refers to /var/run/samba/winbindd/pipe

Regards,
Bruno Andrade.

Hi, have you considered upgrading to the latest sernet packages ? this 
may cure your problems.

[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.
