[RHEL 5] - kdump enabled; node hung - no vmcore autogenerated

Solution Verified - Updated -

Issue

  • kdump enabled.

  • Node found unresponsive, agent reset the system.

  • Should kdump have sensed the hang and have crashed the node creating a vmcore and also rebooting the machine?
  • System was running out of memory and was oom-killing when it was found hung; no ping and console froze.

Environment

  • RHEL 5
  • Kdump enabled
