[Samba] Samba 3.6.9-151 Parse_share modes: buffer too short

[Edginton, Tom S.]

Hi,

I have updated a gpfs cluster of Red Hat servers from 6.1 to 6.4
My previous samba/ctdb configuration was running cleanly, but I now experiencing a number of issues causing instable service of both nfs and samba.

Version of samba:
samba-winbind-3.6.9-151.el6.x86_64
samba-client-3.6.9-151.el6.x86_64
samba-common-3.6.9-151.el6.x86_64
samba-3.6.9-151.el6.x86_64
samba4-libs-4.0.0-55.el6.rc4.x86_64
samba-winbind-clients-3.6.9-151.el6.x86_64

CTDB:
ctdb-1.0.114.5-3.el6.x86_64

Errors:
