The system has 16GB of memory, and the memory pressure looks well below even 50%. This doesn't make any sense. Usually the message starts popping after about 10 days without restarting.

Any light to shed here?

Any light to shed here? I used to have a 12GB hackintosh with Yosemite and this NEVER happened, it lasted stable without restarting for months at a time, this is really ridiculous, I was really expecting for Apple hardware to be more reliable, not less.
