[Samba] winbind memroy leack?

[Marco Rodriguez M.]

Hello,  since two days ago i've noticed that the winbind process take
too much memory and it continue growing constantly.  I have to restart
it every day when it grows to 1.5GB.  I'm using the last stable release
from samba (3.0.20b-24) with ldap backend.    Is there any one who can
help me to discover what is wrong with winbind? i always have above 3
winbind processes running and netstat shows me above 160 conections with
state CONNECTED from winbind, the logs seems to be right there is no
error of any kind.
TIA.
