Morpheus memory usage alerts

[jayst136]

logged in to my newly deployed VME 8.0.13 setup with VME on medium size and 3 hosts with plenty of memory.
all well, but VME manager shows a memory alert/warning (yellow) on the dashboard -> system status. 

So i go look for what it would be about. So i check administration -> health -> health status. Same yellow memory state but no guidance whatsoever on what actually is on waraning state or which threshold is exceeded. Am i looking at the wrong place? 
Also, why would i have a warning? it's doing nothing. 

any insights in what, why and next step?
