I am seeing an error in one of our cluster logs repeating about every minute

> [2016-06-21 15:24:20,401][ERROR][index.engine] [pacesystem][0] failed to acquire searcher, source indices\_ttl java.lang.IllegalStateException: can't locate the origin of the current request at org.elasticsearch.shield.authz.accesscontrol.ShieldIndexSearcherWrapper.wrap(ShieldIndexSearcherWrapper.java:124) at org.elasticsearch.index.engine.IndexSearcherWrappingService.wrap(IndexSearcherWrappingService.java:80) at org.elasticsearch.index.engine.Engine.acquireSearcher(Engine.java:303) at org.elasticsearch.index.engine.Engine.acquireSearcher(Engine.java:287) at org.elasticsearch.index.shard.IndexShard.acquireSearcher(IndexShard.java:849) at org.elasticsearch.indices.ttl.IndicesTTLService.purgeShards(IndicesTTLService.java:200) at org.elasticsearch.indices.ttl.IndicesTTLService.access$000(IndicesTTLService.java:67) at org.elasticsearch.indices.ttl.IndicesTTLService$PurgerThread.run(IndicesTTLService.java:140)

After the error we see the following warning

> [2016-06-21 15:24:20,402][WARN][indices.ttl] failed to execute ttl purge [pacesystem][[pacesystem][0]] EngineException[failed to acquire searcher, source indices\_ttl]; nested: IllegalStateException[can't locate the origin of the current request]; at org.elasticsearch.index.engine.Engine.acquireSearcher(Engine.java:316) at org.elasticsearch.index.engine.Engine.acquireSearcher(Engine.java:287) at org.elasticsearch.index.shard.IndexShard.acquireSearcher(IndexShard.java:849) at org.elasticsearch.indices.ttl.IndicesTTLService.purgeShards(IndicesTTLService.java:200) at org.elasticsearch.indices.ttl.IndicesTTLService.access$000(IndicesTTLService.java:67) at org.elasticsearch.indices.ttl.IndicesTTLService$PurgerThread.run(IndicesTTLService.java:140) Caused by: java.lang.IllegalStateException: can't locate the origin of the current request at org.elasticsearch.shield.authz.accesscontrol.ShieldIndexSearcherWrapper.wrap(ShieldIndexSearcherWrapper.java:124) at org.elasticsearch.index.engine.IndexSearcherWrappingService.wrap(IndexSearcherWrappingService.java:80) at org.elasticsearch.index.engine.Engine.acquireSearcher(Engine.java:303) ... 5 more

Any one know what this means?
