Ok, so did you research these messages to understand what they mean? Did you look for the cause after this?

Hi daphnissov, I did "Google" the errors and found quite a few different posts but a lot of it was confusing to me as I am new to VMware and still learning. Can you point out any helpful links? Thanks!

Turn off admission control and see if it goes away.  If the messages go away and you need Admission Control enabled, you will have to do the proper calculations to configure it properly.

Hi henersp3,

I believe I have Admission Control setup properly:

While I am sure you know way more about your environment than I do I can tell you that Admission Control is a tricky configuration and from the screen shot it looks to be the reason for your message.  Things like slot size calculation can sometimes not be what you expect and might need a look.  If you know about this and have it covered then great.  If not have a closer look.
