samba - Jul 2002 - Winbind problem when heavy loaded ...

Hello, Sambas,

Recently, I met a problem with my Samba 2.2.3a server.
It is configured as a Domain Member, sometimes I couldn't get user list
from PDC ( a Win2k server), but it come up again soon , say 5 seconds.
I had thought it is PDC's problem, but it seems PDC is fine. Are there
any other reasons will cause that? 
Some log messages attached.

Try Samba 2.2.5 - it includes a much improved winbindd, which does much
better connection caching.  The same issue is addressed in smbd by a
mutex.

(These work around NT/Win2k bugs).
