[Samba] Samba hangs over nfs

[Komal Shah]

Hello

1. NFS export:
/srv/nfsexp     127.0.0.1(rw)

2. mount it:
127.0.0.1:/srv/nfsexp /srv/samba/nfs nfs rw,sync 0 0

3. make a samba share and mount it via Windows:
smb.conf:
...
[nfstest]
        path = /srv/samba
        writable = yes
        valid users = tr

Actual results:
As soon as I start to read and write files below
/srv/samba/nfs via Samba on Windows the connection hangs, I get read 
timeout in Explorer

Thanks

Regards,

Komal
