Symptoms

When BIG-IQ is in a high availability (HA) configuration and the active BIG-IQ device cannot communicate with the standby BIG-IQ device, the active BIG-IQ accumulates data in the /var disk partition, which eventually reaches 100% capacity, causing a disruption in services.

Impact

Services do not function correctly.

Conditions

This happens when the active BIG-IQ device cannot communicate with the standby device for an extended period of time.

Workaround

Before taking a standby BIG-IQ system offline, change the active BIG-IQ device to standalone.
