All was working fine until now, a simple SELECT on a measurement fails like this:
> select count(*) from my_measurement
ERR: no data received
> select count(*) from my_measurement
ERR: Post http://localhost:8086/query?chunked=true&db=test&epoch=ns&q=select+count%28%2A%29+from+my_measurement: dial tcp 127.0.0.1:8086: connect: connection refused
> select count(*) from my_measurement
ERR: Post http://localhost:8086/query?chunked=true&db=test&epoch=ns&q=select+count%28%2A%29+from+my_measurement: dial tcp 127.0.0.1:8086: connect: connection refused
> select count(*) from my_measurement
ERR: no data received
At the same time, CPU usage reaches 200%, and memory usage also grows:
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND

I opened an issue on GitHub just in case.
