[hagai yaffe]

Hello,

I am using samba 3.14a on RedHat es3. 

About every day the winbind panics. 
this is the winbind log:

After winbind restart it works ok for about 24 hours and then panics again.
I have seen a similiar post about two years ago with no asnwers.


Any ideas? Need more info?
cheers,
Hagai.
