Symptoms

The hostagentd process on a vCMP host might consume more memory over time.

Impact

Rarely, the vCMP host might run out of memory.

Conditions

BIG-IP appliance or VIPRION blade/cluster with vCMP guests.

Workaround

To work around this issue, you can disable guest health statistic collection on the vCMP host. To do so, perform one of the following procedures: Option 1: Disabling statistic collection for the tmsh show vcmp health command. Impact of workaround: This procedure affects values returned by the tmsh show vcmp health stats command. 1. Log in to the command line of the vCMP host appliance or primary blade of the cluster. 2. To disable statistic collection, type the following command: tmsh modify vcmp guest all capabilities add { stats-isolated-mode }. 3. To restart the hostagentd process, type the following command: a. On a BIG-IP appliance: bigstart restart hostagentd. b. On a blade in a VIPRION cluster: clsh bigstart restart hostagentd. Option 2: Disabling the hostagentd process Impact of workaround: This procedure affects health statistic collection, as well as the ability for guests to install from a host-provided ISO. 1. Log in to the command line of the vCMP host appliance or primary blade of the cluster. 2. To disable the hostagentd process, type the following command: a. On a BIG-IP appliance: bigstart stop hostagentd. b. On a blade in a VIPRION cluster: clsh bigstart stop hostagentd. 3. To exclude the hostagentd process from starting up after rebooting the system, type the following command: a. On a BIG-IP appliance: bigstart disable hostagentd. b. On a blade in a VIPRION cluster: clsh bigstart disable hostagentd.
