    [SOLVED] plasmashell Memory leak?

    I was away from my Linux machine for three weeks (work, not play unfortunately) so I powered it up last night. I didn't do anything special, just browsed the forum a bit. This afternoon I was using my browser, ran updates, and all-of-a-sudden like things got rrrrreeeeallll ssslllllooooowwwww.

    A quick check revealed all 16GB of my RAM was full and 4.3GB of swap was in use! plasmashell was occupying 65.4% of my RAM. Not something I've encountered before. I hadn't rebooted since updating anyway, so I did that. I haven't been back at it long enough to see it return. I was using kernel 4.10.0-27, now updated to -29.

    Anyone else see this?

    Actually the process looks like it's /usr/bin/plasmashell - computer sat idle for about 45 minutes and memory use is up to 10GB for that one process.

                  It's going up and down small amounts as one would expect. I will now add back the clock widget...

                      Any other widgets besides the clock widget adding to the memory leak?

                        Yeah, I added back the Media Frame widget and Event Calendar widget and it went to over 12GB. Then the screen flashed black and it dropped back to 7.1GB. It appears something restarted plasmashell on it's own.
