BIG-IQ DNS
Fixed In:
6.0.1.2
Opened: Feb 21, 2018 Severity: 3-Major
BIG-IQ reports CPU usage for BIG-IP devices at 100% every 10 minutes when using BIG-IQ DNS.
The BIG-IP device cannot manage incoming traffic as expected.
This can happen When approximately 1000 (or more) DNS gslb objects are configured, such as pools of wideips.
None
The GTM state queries to the BIG-IP is now fully synchronous, preventing multiple requests from being sent in parallel. Device CPU still experiences spikes, but if the BIG-IP is too busy then the response is returning with a delay and BIG-IQ will not send next request until the previous request's response is returned.
