influxdb out of memory

### 1. Description:
When running the Influx, the VIRT memory consumption rapidly increases ,and was eventually killed by OOM.

2. Environment:`

[Docker version]:Docker version 1.13.1, build 07f3374/1.13.1
[Docker run command]: docker run -it -d --network host -v /var/lib/influxdb/:/opt/host --memory 10g dfaa91697202 /bin/bash -c "sleep 10000000"
[influxdb version]:InfluxDB shell version: 1.7.0~n201808230800

### [conf]:
influxdb_conf.TXT

[influx logs]:

influx_log_1.zip
Note: 8 hours difference in log time zone

[disk infos]:

I monitored the size of the data , as well as the memory changes, like the following

Start by reviewing influxdb_conf.TXT, influx_log_1.zip, and docker_memory.zip alongside the Docker command and kernel OOM logs. Reproduce the InfluxDB 1.7.0 run with the 10 GB limit, then trace the reported memory growth; done means the cause is addressed and the workload no longer reaches the container limit.
