write_socket_data bug

[Otto Giesenfeld]

I also have the same problem. On RedHat 6.0 and Samba 2.0.7. The samba
server is a member of a Windows 2000/NT domain. Sometimes a client
(Windows 2000 Professional) cannot connect in spite of several attempts,
and then suddenly it works. The network between the clients and the
server is switched, so it cannot be high load that is the problem.
(Besides, the load is quite moderate.)

Did anyone come up with a solution?

Best regards,

Otto Giesenfeld
