Cause

Dell Technologies iDRAC Engineering has identified a memory leak in an iDRAC kernel driver. See the release versions below for applicable fix. It is Dell EMC Engineering's recommendation to apply this urgent update at the earliest available update window. 

  • iDRAC8 - 2.63.60.61 (Early May 2019)
  • iDRAC7 - 2.63.60.62 (End of May 2019)

Resolution

Step-by-Step instructions to update the iDRAC:

 

  1. Go to the Dell support site.
  2. Enter the Service Tag or manually select the model.
  3. Access the menu "Drivers and Downloads"
  4. Select iDRAC from the Category drop down.
  5. Locate and download the latest iDRAC With Lifecycle controller update.
  6. Upload this file to the iDRAC's update and roll back section in order to update the firmware of the iDRAC's (iDRAC will require a reboot)
     
    More information about how to update the iDRAC can be found How to a Remote Firmware Update with the iDRAC?
     

Workaround:

Resetting iDRAC through in-band, out-of-band, or draining flea power will temporarily release the claimed memory space.
