The client might see degraded performance due to request throttling.

Note: This message has been moved to severity notice in newer patch releases

  • Clients may report increased latency that coincides with times when this message is seen
  • The following "lost connection" error may occur when using an ESXi environment.

Lost connection to the server 10.40.1.XXX mount point vmvol, mounted as 14644f70-c8dc684e-0000-000000000000 ("/vmvol")

  • This message is normal and expected when the Oracle dNFS client is in use. It does not indicate a problem
