**Currently:** IWhen the Example run of WBS when WDQS isDocker containers are stopped and restarted without resetting its data volume the followadding or resetting error not always, but often appearsits data volumes, the following error appears and the container stops running:
```

**Goal:** Find the root cause using the Example configuration, determine whether it is a general issue, and fix it.
**Acceptance Criteria:**
[ ] WDQS service remains stable and data accessible / uncorrupted upon container restarts in Example
[ ] WDQS service remains stable and data accessible / uncorrupted upon container restarts in general use
**To Reproduce Issue:**
1) `cd example`
2) `./wbs reset` (choose to reset data)
3) `./wbs start`
4) `./wbs stop`
5) `./wbs start; ./wbs compose logs wdqs-updater -f`
You should see this error appear, and the service will stop.
