NFS client error - A lot of directories

E

eucaly

Hello,

When a lot of directories are shared with the FreeBSD 8.0 or later in NFS Client, it becomes
Code: 
nfsd: RPCPROG_NFS: RPC: Remote system error - Connection refused

There is no problem in the FreeBSD 7.3. When 17 pieces or more are shared, it becomes
Code: 
Connection Refused

Is there a solution?

NFS Server : Microsoft Windows Server 2008.

example :
fstab

Code: 
nfsserver:/00 /nfsshare/00 nfs rw 0 0
nfsserver:/01 /nfsshare/01 nfs rw 0 0
nfsserver:/02 /nfsshare/02 nfs rw 0 0
nfsserver:/03 /nfsshare/03 nfs rw 0 0
nfsserver:/04 /nfsshare/04 nfs rw 0 0
nfsserver:/05 /nfsshare/05 nfs rw 0 0
nfsserver:/06 /nfsshare/06 nfs rw 0 0
nfsserver:/07 /nfsshare/07 nfs rw 0 0
nfsserver:/08 /nfsshare/08 nfs rw 0 0
nfsserver:/09 /nfsshare/09 nfs rw 0 0
nfsserver:/10 /nfsshare/10 nfs rw 0 0
nfsserver:/11 /nfsshare/11 nfs rw 0 0
nfsserver:/12 /nfsshare/12 nfs rw 0 0
nfsserver:/13 /nfsshare/13 nfs rw 0 0
nfsserver:/14 /nfsshare/14 nfs rw 0 0
nfsserver:/15 /nfsshare/15 nfs rw 0 0
nfsserver:/16 /nfsshare/16 nfs rw 0 0
nfsserver:/17 /nfsshare/17 nfs rw 0 0

error:

Code: 
Mounting late file systems:[tcp] nfsserver:/16: nfsd: RPCPROG_NFS: RPC: Remote system error - Connection refused.
 
Both end up with a "Connection refused", the one on 8.0 is just a little more detailed. The end result is the same.

Either way it's a problem with the NFS server, not the client.
 
Thanks.

However, the reason why the FreeBSD 7.3 is good and the 8.0 is useless is not understood.

An additional verification was done.

NFS Server -> NFS Client
FreeBSD 7.4 -> FreeBSD 8.2 : over 18 Directory OK.
WS2008 -> FreeBSD 8.2 : It fails because of piece 17.
WS2008+FreeBSD 7.4 -> FreeBSD 8.2 : WS2008 16 Directory + FreeBSD 7.4 18 Directory OK.

WS2008 -> FreeBSD 7.4 : over 18 Directory OK.
WS2008+FreeBSD 7.4 -> FreeBSD 7.4 : WS2008 18 Directory + FreeBSD 7.4 18 Directory OK.

WS2008 Used NFSv3.
use OS : FreeBSD 8.2-RC2/AMD64 and FreeBSD 7.4-RC1/AMD64

showmount -e results all mount-points. (both 8.2 and 7.4)
 
OK. It works!.

When the Microsoft Windows Server NFS Service is used, it might be good if it makes it to the "UDP".

fstab:
Code: 
nfsserver:/00 /nfsshare/00 nfs rw,udp 0 0
nfsserver:/01 /nfsshare/01 nfs rw,udp 0 0
nfsserver:/02 /nfsshare/02 nfs rw,udp 0 0
nfsserver:/03 /nfsshare/03 nfs rw,udp 0 0
nfsserver:/04 /nfsshare/04 nfs rw,udp 0 0
nfsserver:/05 /nfsshare/05 nfs rw,udp 0 0
nfsserver:/06 /nfsshare/06 nfs rw,udp 0 0
nfsserver:/07 /nfsshare/07 nfs rw,udp 0 0
nfsserver:/08 /nfsshare/08 nfs rw,udp 0 0
nfsserver:/09 /nfsshare/09 nfs rw,udp 0 0
nfsserver:/10 /nfsshare/10 nfs rw,udp 0 0
nfsserver:/11 /nfsshare/11 nfs rw,udp 0 0
nfsserver:/12 /nfsshare/12 nfs rw,udp 0 0
nfsserver:/13 /nfsshare/13 nfs rw,udp 0 0
nfsserver:/14 /nfsshare/14 nfs rw,udp 0 0
nfsserver:/15 /nfsshare/15 nfs rw,udp 0 0
nfsserver:/16 /nfsshare/16 nfs rw,udp 0 0
nfsserver:/17 /nfsshare/17 nfs rw,udp 0 0

But.
It doesn't know the performance....;
