To Reproduce
Steps to reproduce the behavior:

1. EMBArk installation (default mode)
2. Start EMBArk: sudo ./run-server.sh
3. After startup completes, shut down EMBArk using Ctrl-C
4. See error

Expected behavior
While expecting some warnings on shutdown, an error about incorrect thread contexts seems rather severe (especially involving database operations).
