I have a problem with my Gitlab installation running on a small Ubuntu LTS 16.04. I have to point out that I don't have much experience with Linux or Gitlab.
My Gitlab installation with a few personal projects (only 4) was running Ok, though pushing is extremely slow and sometimes fails. Also accessing the web interface is extremely slow. I checked the server and noticed that up to 96% of total memory were used. The culprit seems to be a bundle process.

I've hit pstree and these bundle processes seem to be related to the ruby application (must be gitlab).
systemd─┬─agetty
├─atd
├─bundle─┬─3*[bundle───{ruby-timer-thr}]
│ └─{ruby-timer-thr}
...
Does anyone have had similar experiences or an idea what might cause this?
