Mysqld and bcm56xxd seem to run at 100% on vCMP host.


This results in the hypervisor not functioning properly.


When the hypervisor collects statistical data from itself and all hosted guests, too many system resources are used, leading to constant updates of data to mysql.


Execute the following command: bigstart stop monpd. Impact of this workaround: Although no statistical data will be collected, the hypervisor will perform all other functions.

Fix Information

The sampling rate of statistical data was reduced, and samples only the required data for vCMP. As a result, collecting statistical data does not cause a serious impact to system performance, so the vCMP guest no longer experiences potential frequent failovers.
