RAM usage is stuck

Hello everybody,

I have set up an own hosted Jitsi Server (VM) with 8 CPUs an 16 GB of RAM.

The problem is that the Videoconnections are unsable and the video or tone is interrupted.

As i tracked the RAM usage I recognized that it rised up to ~10 GB over about 4 to 5 hours and stayed there until the next restart.

I am using Ubuntu 18.04 LTS and the Jitsi Releas 2.0.5076.

Do I have to modify any file so the RAM usage decreases again? And why doesn`t it use more then 10 GB of RAM?

Thanks for your help.
