Hi,

I don't know how much is this related to this list  but I am posting it here in case you guys can post some ideas.

I have a NFS server domU with two AMD optereon 2.1GHz  vcpus. RAM is 1GB  with 2GB of SWAP space. A second server (not a virtual machine) gets its nfs share from the domU which is exported via /etc/exports.

The NFS share is mounted using auto_direct in the second server and it looks like:

/usr/local/content    -rw,hard,retry=3,timeo=120,intr,rsize=16384,wsize=16384        nfs.xxx.com:/usr/local/nfs/

Now the problem is if I see the output of dmseg in the second server in which the nfs share is mounted. I see:

--
Apr 22 17:01:56 nfs: [ID 333984 kern.notice] NFS server nfs.xxx.com not responding still trying
Apr 22 17:02:00 nfs: [ID 563706 kern.notice] NFS server nfs.xxx.com ok
---

It is working but I am seeing this message. I am assuming this is making the data transfer slow.

Any idea on improvements?

Thanks!
Paras.
