Ubuntu 18.04 gnome shell memory leak

in #ubuntu6 years ago

Memory leak of gnome shell under ubuntu 18.04 LTS

After some time gnome shell uses 62% of the memory, I also had several times situations where the memory consumption did go to full system memory (16 GB) & swap (also 16GB) usage, meaning the system almost didnt react anymore.

I saw this happening mostly when using the Unity3d editor and importing many assets into my project. - in my example it was about 10 assets using around 30 GB diskspace after import. (without unity import compression) - hint: unity3d editor memory usage was between 2-3 GB while processing asset import.

When I enable the Unity3d import compression option, most times my gnome shell goes out of memory. Interstingly the jumps in memory consumption often happens abrupt and intensive increase in memory consumption of gnome shell happens.


output of top command looks like this:
