Is it possible for currently running jobs in MySQL to utilize memory that’s been hot added? It looks like when memory is hot added to the VM the currently running jobs are not utilizing the additional memory.
Answer
Schedule downtime and reboot your VM. Memory hot-add isn’t really that great.
You may have other issues in your VMware environment like a hard memory limit assigned to the VM. Make sure that you don’t have any.
