High CPU utilization may occur on HPE systems running HPE Agentless Management Service (iLO 5) for Linux (amsd) earlier than version 1.4.0. In addition, one or more of the following system log entries may occur: smad: Failed: Timed out waiting for SNMP_HELLO response hpilo 0000:01:00.2: Open could not dequeue a packet hpilo 0000:01:00.2: Closing, but controller still active smad: Failed: no available HP iLO channels smad: Failed: Writing HPILO SNMP_HELLO errno =9 hpilo 0000:01:00.2: Open could not dequeue a packet hpilo 0000:01:00.2: Closing, but controller still active These issues are a result of an accumulation of ungraceful amsd shutdowns. These ungraceful shutdowns can result in HPE integrated Lights-Out 5 (iLO 5) losing track of the communication channels; therefore, a communication failure occurs with amsd. When amsd polls the failed communications channels, high CPU utilization occurs.
