Memory consumption is increasing gradually. Why is there so much memory used and should I be concerned?

Environment
Release : 3.3.x
Component : PRIVILEGED ACCESS MANAGEMENT
Resolution
1. This is a normal behavior and actually a good thing (that MySQL claims whatever available RAM it can claim and put them to good use.)
2. Most of the memory allocated was the "Buffer" and more buffer generally means more performance. If this buffer cannot be allocated then MySQL will get the data from disk which will be much slower and will impact performance.
3. There is a patch(Hotfix 3.3.2.11) which can reduce the memory usage by MySQL at the cost of performance.
* As this would impact performance, you need to raise a support ticket to get this patch.
* It requires a reboot so you will need to schedule a down time.
As long as you are not experiencing any issue, recommendation is to let MySQL do what it is supposed to do.
