kipmi kernel helper thread kipmi0 is generating high CPU load

Solution Verified - Updated -

Issue

  • The kipmi0 kernel helper thread sometimes goes to 100% CPU usage. Once there, it remains at 100% until the next reboot. After a reboot, things return to normal and then, at a random time later, it goes to 100% again.

  • Performance discrepancies in application throughputs between otherwise-identical RHEL hosts may implicate KIPMI.

Environment

  • Red Hat Enterprise Linux 4
  • Red Hat Enterprise Linux 5
  • Red Hat Enterprise Linux 6
  • Out-of-band management hardware that supports the Intelligent Platform Management Interface (IPMI, a systems health and management standard supported by multiple vendors)
