Error when setting socket options

[Eirik Thorsnes]

I get the following error in the smb log:

[2000/01/06 11:17:46, 0] lib/util_sock.c:set_socket_options(148)
  Failed to set socket option SO_KEEPALIVE (Error Bad file descriptor)

[2000/01/06 11:17:46, 1] lib/util_sock.c:client_name(997)

Any suggestions on what to do to solve this / get more
information?

I am running a Redhat 6.1 system, samba 2.06 - compiled from tarball.
I have this NIC:
class: NETWORK
bus: PCI
detached: 0
driver: eepro100
desc: "Intel Corporation|82557 [Ethernet Pro 100]"
vendorId: 8086
deviceId: 1229

Thanks in advance
