Hi again @piero_cory,
The issue seems to be caused by a wrong order in the shutdown of services when the VM is rebooted or halted. The scripts that manage Eclipse Che always check that Docker is running properly but during system shutdown, Docker is stopped before Eclipse Che and this causes the latter to be forcibly killed after a timeout.
As a workaround, if you're using VirtualBox, you may use the "Save the machine state" feature instead of rebooting it. Alternatively, you may log into the VM and stop the services manually before reboot or shutdown by running the following commands:
sudo /opt/bitnami/ctlscript.sh stop
Hope it helps.
