Since the leaking began I have been filling to about 2/3 of max.
I now have a new reservoir.
Based on Sleepriders comments I did a test. First of all remember that I previously checked the reservoir for leaks by filling it and letting it sit. No leaks. Now, I put water in it and put my finger over one hole while blowing into the other. It leaks like crazy right out of the bottom where the metal heating plate meets the plastic.
Now we know. The reservoirs wear out and leak in time.
How long had these been in use before they began leaking? I have had my Airsense 10 for 22 months and have replaced the reservoir once, after approximately one year, when it developed a slight leak. I assumed it was at the joint between the plastic and metal base.

I will update tomorrow.
I did the same test today and got no leaks. It's pretty easy apply pressure to the reservoir, but I had not thought of it until today.

I've had 3 reservoirs in about 2.5 years. The two I still had were leaking. I think that's part of what threw me off, thinking at least one had to be good. Periodically I use vinegar to dissolve calk build up on the warm plate. Perhaps that has a negative effect on the sealant. I have two new ones now. On the pressure test the leak was substantial.

Should have some answers in the morning.
If you getting that much buildup, then you may do better by using distilled water. It makes cleanup and maintenance much easier. With distilled water, you can cut back on the vinegar. It doesn’t hurt, but shouldn’t be overdone. Also, don’t let the water sit in your water chamber, get rid of it daily.

If your Resmed AirSense 10 leaks then you need to pressure test the reservoir. Too bad the bottom half of the reservoir isn't made of a single piece of stamped metal for longevity.
If you look closely at your AirSense 10 reservoir the bottom half is composed of three pieces.
1, The sides which is the main body of the bottom half.
2, The metal heat exchanger plate.
3, The plastic bottom plate.
The actual waterproof seal is between the side part and the heat exchange plate. The bottom plastic plate is there for rigidity and if you look closely at it there is a drain hole and no sealant where the heat exchanger plate is exposed. If you see any moisture between the plastic bottom plate ant the metal heat exchange then your reservoir has already failed and it will only get worse. Now, take a close look at the seal between the heat exchanger ant the side body. In mine, there are minor inconsistencies in the sealant and there are small gaps evident. You have to look pretty close.
Conclusion;
It's a good idea to look at your reservoir. If you see any moisture below the heat exchanger then you can expect problems.
