The solution is stable.

The SAS/ACCESS product is as stable as you can get. SAS will give you plenty of heads up if you have a licensing issue or if there is a newer version coming out. They will send you a full download link and a link to information that explains why you need to upgrade, along with the timeframe you have to apply the upgrade. They stay on top of keeping the product running. It is about as stable from a software environment perspective as I can imagine. It really goes along with their whole philosophy of the support picture.  

The solution is very stable. There aren't issues with bugs or glitches. It doesn't crash or freeze. It's reliable.
