[Samba-it] winbindd in panic-action

[Marco De Vitis]

Salve a tutti.
Ho una macchina che fa da proxy in una LAN, con squid, autenticando  
gli utenti sul database di un'altra macchina che fa da PDC. Entrambe  
montano Debian Sarge con Samba 3.0.23, anche se sul proxy non c'è  
Samba "completo" visto che usa solo winbindd per la partecipazione al  
dominio.

Da stanotte, di punto in bianco, il proxy ha iniziato a spararmi  
centinaia di email di errore con il testo che allego sotto. Sembra  
che a un certo punto il processo figlio di winbindd inizi a morire in  
continuazione. Sto ancora cercando info e facendo altre prove, ma se  
nel frattempo qualcuno ne sapesse qualcosa... altrimenti domani  
niente internet per i miei utenti :-P.
