As Col. Potter would say .. "HORSE HOCKEY!!" I have gotten the same error several times with 8G of RAM and 750G free on my HDD.

Then something else is wrong because the absolute only reason that dialog would show up, is if the system is out of regular ram and also can't page out to disk anymore.
 
Spoke too soon. It's back with a vengeance! Mail goes from 200 meg to 60 gigs of memory in seconds.
 
I haven't installed Yosemite yet but it seems it does indeed eat alot of RAM,in this video (final release not beta) it takes 7GB of 8GB and thats without sny apps running :

(Jump to minute 1:50 were he shows activity monitor).

I wonder how well it will work with just 4GB,as thats what all Macbook Air come as standard and there is no upgrade option..
 
I have 8GB of RAM and yosemite using 7.9GB of RAM. if you read about memory usage in OS X and post mountain lion you will see that this intended.

the indication of ram problem is in memory pressure graph not memory used

True, but if Mail is using 60 GBs of memory, then there is a real issue.
