No issue starting Mechanical as a docker Container, but unable to restart container.

[peak-rvanderploeg]

With my mechanical docker image set up, I can start mechanical with the following and it runs fine:
docker run -e [email protected] --name mechanical -p 10000:10000 c3b4ac40
After stopping that container for any reason (such as a crash), upon restart I get the following in my container logs:
xvfb-run: error: Xvfb failed to start
and sure enough it doesn't start back up. The only way to get it working again is to delete the container and make a fresh container from the image. If you have any ideas on how to fix this please let me know!

I'll answer myself here so others can see in the future. If the container is killed while busy it seems it does not die gracefully, and this will cause xvfb errors upon restart. If you stop/restart the container while it is not busy, then xvfb has no issue restarting.
