samba and crash server

[Oleg Novikov]

Hello All!

 We  use  Samba  3.0.14a  as  PDC on server with dual P4 Xeon processor.
 Earlier  we  use  previos  version,  but  problem  is same. On server
 instaled SLES 9.

 When samba working in system is occur process with status D, i.e.
 #ps ax
 9264 ?        S      0:00 /usr/sbin/smbd -D -s /etc/samba/smb.conf
 9265 ?        S      0:00 /usr/sbin/smbd -D -s /etc/samba/smb.conf
 9272 ?        D      0:00 /usr/sbin/smbd -D -s /etc/samba/smb.conf
 9274 ?        D      0:00 /usr/sbin/smbd -D -s /etc/samba/smb.conf
 9281 ?        D      0:00 /usr/sbin/smbd -D -s /etc/samba/smb.conf
              ^^^

 The  quantity  of such processes quickly grows. We cannot kill any of
 this process. In few minutes the server is cannot make anything. Then
 we  press  reset  on  server, but in some time this error is repeated
 again.
