The first, third and fourth nodes post this in a busy loop:
E171109 11:18:43.095282 6355217 sql/lease.go:992 background lease renewal for tableID=55 tableName=“blocks” failed: descriptor not found
E171109 11:18:43.101027 6355246 sql/lease.go:992 background lease renewal for tableID=55 tableName=“blocks” failed: descriptor not found
E171109 11:18:43.105208 6355253 sql/lease.go:992 background lease renewal for tableID=55 tableName=“blocks” failed: descriptor not found
the third node has no such flurry of errors, but instead
E171109 11:19:55.066369 150 sql/jobs/registry.go:154 error while adopting jobs: database “system” does not exist
Additionally, two of the four block writers spam
