After one day my memory usage goes up to 91%. gnome-shell is part of the problem, but it seems like other programs are also holding memory as well. I am using the nouveau driver because Nvidia will not load the gdm hangs on boot with Nvidia. I have 8 gigs of memory and the Nvidia card is
== /sys/devices/pci0000:00/0000:00:02.0/0000:01:00.0 ==
modalias : pci:v000010DEd00001082sv000010DEsd00000873bc03sc00i00
vendor : NVIDIA Corporation
model : GF110 [GeForce GTX 560 Ti OEM]
driver : nvidia-driver-390 - distro non-free recommended
driver : nvidia-340 - distro non-free
driver : xserver-xorg-video-nouveau - distro free builtin
Both drivers for Nvidia hang up and the I am not sure where to go on the memory leak.
Any ideas would be gratefully appreciated.
Restarting plex media server corrected the problem. However, now I have to figure out why plex media server keeps eating memory.
