**Currently:** When the Example Docker containers are stopped and restarted without adding or resetting its data volumes, the following error appears and the container stops running:
```
12:55:33.443 [main] INFO org.wikidata.query.rdf.tool.Update - Starting Updater 0.3.135 (993993ebef2c4c06d98aaa24767edef029bee287)

12:55:33.897 [main] INFO o.w.query.rdf.tool.rdf.RdfRepository - Found left off time from the updater
12:55:33.897 [main] ERROR org.wikidata.query.rdf.tool.Update - Error during initialization.
java.lang.IllegalStateException: RDF store reports the last update time is before the minimum safe poll time. You will have to reload from scratch or you might have missing data.

**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.
