High CPU usage for one measurement

Store
1

influxdb ver 1.6.4

We noticed that queries only one particular measurement cause the CPU to spike up.

I have the outputs for
curl -o vars.txt “http://localhost:8086/debug/vars”
curl -o profiles.tar.gz "http://localhost:8086/debug/pprof/all

I used what you have here and saw no problems:
