Original Document Release.

When sending any of the below traps to an HP ProLiant server running Red Hat Enterprise Linux 6 with HP SNMP Agents (hp-snmp-agents) Version 9.30 (or earlier), the hp-snmp-agents function of cmanicd (NIC agent) will segfault, requiring the hp-snmp-agents to be restarted to regain functionality of cmanicd:

 


When this occurs, a message in the operating system log similar to the following is displayed:

 

SCOPE

Any HP ProLiant server running Red Hat Enterprise Linux 6 and HP SNMP Agents Version 9.30 (or earlier) when receiving SNMP v1 Linkup or Link down MIB traps.

RESOLUTION

This does not occur with the HP SNMP Agents Version 9.4.0 (or later).

Perform the following steps to obtain the latest version of the HP SNMP Agents:

  1. Click on the following link:

    http://www.hp.com

  2. Select Support > Download drivers
  3. Enter a product name (e.g., ProLiant DL360p Gen8) and click on Go.
  4. Select the specific ProLiant model.
  5. Select the appropriate Linux operating system.
  6. Click on the category Software - System Management .
  7. Locate, download, and install HP SNMP Agents for Linux Version 9.4.0 (or later).

Until the HP SNMP Agents Version 9.4.0 (or later) are installed, to avoid the NIC agent segfault, remove the NIC agent by excluding the cmanicd from loading with the hp-snmp-agents (add cmanicd to exclude line) via /opt/hp/hp-snmp-agents/cma.conf.

If the NIC Agent has already stopped responding, restart the HP SNMP Agents by typing the following command to regain functionality of cmanicd:

service hp-snmp-agents restart
