Hi, I was trying to track down a strange issue in my monitoring app and influxdb is not returning data from some queries like:  
`SHOW TAG VALUES WITH KEY = "host"`

which has been working for a few months, but data is certainly there.

```
memory_percent_cached,host=tf-p-ubu-sensu-00,metric=memory-percent-metrics
memory_percent_cached,host=tf-p-ubu-statsd-00,metric=memory-percent-metrics

```

i am stumped on what happened, I dont see any errors in the log excepts for

`2018-03-12T06:44:25Z error writing snapshot: error opening new segment file for wal (1): close /data/influxdb/lib/influxdb/wal/statsd/autogen/1/\_00001.wal: file already closed engine

thanks in advance for any help…
