When an application or operating system causes a compute node to hang, in some cases, it is observed that the node’s ILOM becomes unresponsive as well, making it impossible to remotely reset the node.  Recovery from this state requires a manual power cycle of the compute node in the data center. This leads to extended downtime and inconvenience, especially if the data center is remote and unmanned.
