Every long period of usage, usually a half hour to an hour, a memory leak by the plasmashell process occurs. Reproducible: Always Steps to Reproduce: 1. Use the plasma environment for an extended period of time Actual Results: The plasmashell process takes up all available memory, dragging the computer to a near halt. Eventually the process is killed and when restarted everything returns to normal. I was able to get a screenshot of top before the computer became unusable (apologies for the small font because I need to keep it running always-on-top in order to catch it fast enough): http://i.imgur.com/alHON3A.png Expected Results: The plasmashell process would not use an exorbitant amount of memory. KInfoCenter reports a quad core Intel N3540 at 2.16 GHz with 3.7 GiB of RAM I apologize that I don't have a lot any debugging data to share because I don't know what exactly to do for that. I will be happy to try giving any debug data that's instructed to me to collect.
Created attachment 98121 [details] additional info I am having the same issue. The plasmashell process will start out using about 220MB of memory and after an hour become about 1.5GB memory usage. I am running this on Kubuntu 15.10, Plasma verison 5.6.90 from the Neon repository Hardware: Intel 4690K 8GB DDR3 Nvidia GTX 970 running driver 352.63
