[Samba] Error was Transport endpoint is not connected

[robert.gehr]

Hello All

I used to back up a Mssql database (about 55GB) to a samba share without
any problems. The samba server "Server-A" was running version 3.4.7
We just got one of those "Netgear ReadyNas3200" things and I tried to
backup up to a share there which sometimes works and sometimes not in
wich case I get the following error:

----------------snip---------------

[2010/10/08 21:32:26.937834,  0]
lib/util_sock.c:474(read_fd_with_timeout)
[2010/10/08 21:32:26.966404,  0]
lib/util_sock.c:1432(get_peer_addr_internal)
  getpeername failed. Error was Transport endpoint is not connected
  read_fd_with_timeout: client 0.0.0.0 read error = Connection reset by
peer.

---------------snap-----------------

The samba version on the ReadyNas is 3.5.4

On the windows side nothing has changed apart form the destination to
the new share. The ReadyNas performs pretty well and I do not get any
network errors or otherwise. To rule out some network problem I exported
a nfs share on the ReadyNas which I mounted on "Server-A", created a
share on "Server-A" that points to the nfs-mount and ran a backup. No
problems and no errors.

Any ideas which buttons to push in order to get a reliable backup going
again? From what I read this usually points to a problem on the client
side but nothing has changed there. I could of course use the
"Server-A:smb->nfs-mount:ReadyNas" solution but this is not what I want.

Thanks
