BIG-IP CGN, Install/Upgrade
Known Affected Versions:
12.1.0, 12.1.0 HF1, 12.1.0 HF2
Opened: Apr 05, 2016
You notice unusually high CPU utilization on Virtual Edition after upgrading to 12.1.0 when compared to a previous release (such as version 11.6.1).
Since CPU0 is unusually high compared to previous releases, upgrading could put Virtual Edition into an overloaded state.
This occurs after upgrading to 12.1.0. In Virtual Edition version 12.1.0, there is an issue where network interface IRQs don't get pinned correctly at startup.
bigstart restart tmm will start the network interfaces and pin them to the right IRQ.
Fixed an issue where interfaces and their IRQs were not configured correctly during system boot.
