I have two error messages on user.log as follow :

1.
[2001/11/26 14:41:07, 0] smbd/oplock.c:oplock_break(813)
  oplock_break: no break received from client within 30 seconds.

Here is the information of my system :
- Samba server 2.2.2-6, rpm install on a RedHat 7.2
- Kernel 2.4.7-10.

and my smb.conf file :

[global]
        smb passwd file = /etc/samba/smbpasswd
        dns proxy = no
        security = user
        encrypt passwords = yes
        workgroup = estudio
        server string = Samba Server
        socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
        log file = /var/log/samba/%m.log
        netbios name = servidor
        preferred master = yes
        max log size = 0

[homes]
   comment = Home Directories
   browseable = no
   writable = yes
   valid users = %S
   create mode = 0664
   directory mode = 0775

   comment = Archivos de Sistema
   path = /sistema
   public = yes
   writable = yes
   create mode = 0664
   directory mode = 0775

   comment = Archivos de la central
   path = /files/central
   public = no
   writable = yes
   printable = no
   valid users = emilia
   create mode = 0664
   directory mode = 0775

[contable]
   comment = Archivos de contable

   public = no
   writable = yes
   printable = no
   valid users = @contable

   directory mode = 0775


I´d like to know the meaning of the error messages and/or where can I get
the meaning of different errors ?

Thanks and Regards
