A small cluster runs well before this major upgrading. After upgrading, the cluster has some NFS related weird issues.
A shared 3rd party package (compiled from source) is deployed on a NFS drive directory. Some times the shared computing program works fine, but frequently the shared computing problem aborts randomly on some nodes because of unknown issues. When the problem happened, I logged on that node, and tried to cp the execute file to /tmp, the copy process hanged up, but I successfully copied other files without issues and can create new files on NFS drive.
I am totally lost here, what should to diagnose the issue?
Currently, the system uses amd64, the kernel uses ~amd64. The NFS is deployed using the howto:

The package installed are ntp, ssh, rsh, nfs.

Could someone, who has a stable working NFS server, do me a favor, paste the related configure files, /etc/fstab on NFS clients, /etc/conf.d/nfs and /etc/exports on NFS server? What is the kernel version and nfs-utils version?
Thanks in advance.
