HUD service memory leak (ubuntu 16.04)

[J]

Large or very frequent memory leak, realized of it when my system started to need the swap space (not frequent as I usually don't consume more than half of my 16 GB of RAM). The HUD service had 13 GB of the memory used up.

I had the same problem. Hud service using GBs of RAM and CPU always at 50%+. Also the thumbnails of files in nautilus were not showing. In my effort to fix thumbnails I granted permission of ~/.cache/thumbnails for the user. then everything has solved. hud-service using only 11.5MB of RAM. CPU below 5%.

Status changed to 'Confirmed' because the bug affects multiple users.

I have the same problem. CPU at 30% and using 3G of memory. Only "solution" I have found so far is to reboot system

You can remove the execution right from hud-service with command

"sudo chmod -x /usr/lib/x86_64-linux-gnu/hud/hud-service"

to prevent hud-service from launching
