  • The ESXi host displays a purple diagnostic screen
  • The purple diagnostic screen contains backtraces similar to:

  • HP IML logs or System Event log (SEL) may report NMI error similar to:

    An Unrecoverable System Error (NMI) has occurred (System error code 0x00000032, 0x10426844)


VMware ESXi 4.1.x Embedded
VMware vSphere ESXi 5.0
VMware ESXi 4.1.x Installable
VMware vSphere ESXi 5.1
VMware vSphere ESXi 5.5


This issue occurs due to the interaction between HP CRU driver and system ROM BIOS while handling corrected ECC errors.


This issue is resolved in the BIOS released on 5/10/2011 or later. For more information, see the HP Customer Advisory c03065184 and BIOS System ROM dated 05/xx/2011 or later.

Note: The preceding link was correct as of October 22, 2013. If you find the link is broken, provide feedback and a VMware employee will update the link.
To work around this issue, disable the smx provider.
  1. Connect to the ESXi host using the vSphere Client or vCenter Server.
  2. Click Host > Configuration > Software > Advanced Settings > UserVars.
  3. Change the UserVars.CIMoemProviderEnabled value from 1 to 0.
  4. Run this command to restart sfcbd:

    # /etc/init.d/sfcbd-watchdog restart
