[Samba] lost connection to w2k3 -> very slow system

[halemb]

Hello

I am using samba 3.0.10 connected to w2k3 (domain member) via winbind. 
Everythings works ok, but when linux (winbind) lost connection to w2k3 system 
works very slow. 
e. g. 
Loging to console -> 1min 10sec
Apache server -> I cannot refresh web site

usage cpu is ok -> about 5%
usage mem is ok too,

When I restart winbind or kill them everything works good.

What is wrong???
I have the same problem when I connected to w2k3 using 'net ads 
join' (kerberos)  and when I using 'net rpc join'.
