InfluxDB stops writing

1

I am writing data to influxdb using the node-influx library.

I am using influx.writePoints to do the writes as explained here,

https://node-influx.github.io/manual/tutorial.html

The only tweak I made is insert in batches. The batchsize is set to 10000.

It writes about 500,000 records and then I start seeing this error following which there are no more writes. It looks like a dns issue but I am running it inside a docker container on ubuntu 18.04 host.

Error: getaddrinfo EAGAIN influxdb influxdb:8086 |at GetAddrInfoReqWrap.onlookup [as oncomplete] (dns.js:56:26)

I have the logging level set to debug but I am not seeing any other errors.

I am able to write using curl even after the error

Update
I am using a worker container to do the writes and the error is happening on it. If I restart this container after I get the error, the writes start happening again for another 500,000 points and then I get the same error.
It could be a connection issue from the worker to influx

Here is the output of

curl http://localhost:8086/debug/vars | jq

    "name": "httpd",
    "tags": {
      "bind": ":8086"

  }
}

As you can see I am not seeing any failures here. It looks like I am running into some limit here, I have already upped the ulimit on the host.
