Severity: 3-Major

Symptoms

BIG-IQ makes iControl REST requests to BIG-IP systems to get statistics. Regardless of the page size setting, the request causes the CPU to spike to 100% utilization.

Impact

Frequent requests by BIG-IQ for stats causes repeated spikes.

Conditions

An iControl REST API request from a BIG-IQ device for a few stats for an object on a BIG-IP system. Note: A request for a single statistic usually does not cause a spike.

Workaround

None.

Fix Information

None
