unstable!!!

Hi.
We add a new virtual machine with vmware server 1.0.4, centos 5.x
client, we update the server with yum and receive samba
3.0.25b-1.el5_1.4, we have a PDC running Gentoo with Samba
3.0.24+ldap, all the windows clients and other Linux boxes(.3.0.10 +
3.0.23 + 3.0.24) are working very good and stable.
The only problem is this new server, i read about some changes
with samba 3.0.25b and oldest version, since we add this server to the
domain we had been having problems, we enable the roaming profile to
our windows clients, but some times the server doesn't update the user
profile, on other situations we lost the profile, example firefox
settings, or if the user update some excel file next day appear with
no changes.
We have almost 3GB of core dumps since we setup samba inside
winbind folder, look this is my smb.conf file:
[global]
workgroup = mydomain
server string = mydomain VM DBA Server

bind interfaces only = Yes

Look now, this winbind logs:
