logon errors, write_socket_data: write failure. Error = Broken pipe

[Lee Howard]

I'm having authentication (logon) errors occasionally.  After trying to log
on for a few minutes eventually it will succeed.  I'm using samba-2.0.7 on
RedHat 6.1 (updated).  The samba logs look like:

[2000/10/23 14:03:24, 0] lib/util_sock.c:write_socket_data(540)

Does anyone have a clue as to what could be wrong?

thanks.
