Error Bad file descriptor

[Paulo Juliano Horlle]

    Dear friends,

    I receive the error "Error Bad file descriptor" when samba start, the
socket option in smb.conf have the line: "socket options = TCP_NODELAY
SO_KEEPALIVE SO_SNDBUF=4096"
My distribuition is Red Hat 6.2 and the Samba version is 2.0.69.

This is the error log /var/log/samba.smb:

  file_init: Information only: requested 10000 open files, 1014 are
available.

    Where are the problem, in Samba or in lib/util_sock.c?

    Please, my network is very slow without TCP_NODELAY.

    Best Regards!
