[Samba] kernel error smb_errno: class ERRSRV, code 91 from command 0x32

[Adi Nugraha]

Hi,

I have a samba +ldap PDC running on mandrake 10.0 the server is running
great except for the error mesage in the kernel log, whic I think causes the
system to crash  after some time, how much time is needed is unknown, but it
seems to get faster with increasing user, as this was a first attempt I
first tried it with only less than 10 users, and it the server would go on
for more than 3 months, by now I have almost 90 users, and the server seems
to crash after around a week, does anyone know what this means, any help
would be appreciated
here are the log from the kernel
