rnode table overflow

rnode table overflow

If an NFS client tries to access too many files simultaneously (including mount points, directories, and running binaries) in remote NFS-mounted filesystems, you may see the following error message: 

   nfs_iget: rnode table overflow
The default maximum number of remote files that a client can access simultaneously is 256. To increase this number:

  1. Log in as root on the client and run the scoadmin(ADM) Network Configuration Manager or netconfig(ADM).

  2. Highlight SCO NFS Runtime System.

  3. Select Modify protocol configuration from the Protocol menu.

  4. Increase the number of NFS connections and click on OK.

  5. Exit the Network Configuration Manager and select to relink the kernel when prompted.

  6. Shut down and reboot the system for the change to take effect.
