Hi Michael, I am having exactly identical issues here, running an imac retina 5k late 2014 with 16gbs ram, and running pitstop with acrobat. (Although with or without pitstop running it does the same thing). This only started last week and there have been no hardware or software changes to my system... unless adobe acrobat has done some sort of update in the past week? And my system does the same... after a small amount of time acrobat pro dc will be paused and then anything else I have running, which then requires a machine restart. The only way to stop it is to restart acrobat every hour or so, even If I have not done anything with it, it just keeps bloating out and using all the ram available. Why is this just started and what is the cause? And also here, this only happens with acrobat running. I have never had a memory issue at all on this computer until this past week, and now it is constant and seems to be solely due to acrobat.
