+#### 5.1) Chromium crashes with high VNC_RESOLUTION ([#53](https://github.com/ConSol/docker-headless-vnc-container/issues/53))
+If you open some graphic/work intensive websites in the Docker container (especially with high resolutions e.g. `1920x1080`) it can happen that Chromium crashes without any specific reason. The problem there is the too small `/dev/shm` size in the container. Currently there is no other way, as define this size on startup via `--shm-size` option, see [#53 - Solution](https://github.com/ConSol/docker-headless-vnc-container/issues/53#issuecomment-347265977):
