**BUG REPORT**
When the Bookie tries to flush the MemEntryTable on an `addEntry` it started
to spam the log "Reached size null".
***Describe the bug***
```
20-05-04-00-02-44 Reached size null

***Expected behavior***
I expect that if it can't flush the checkpoint for this type of Exception
the service stops
