Multiple ports from Kibana to Elasticsearch in TIME_WAIT

Elastic Stack Kibana
1

I am running Kibana version 4.5.0 and Elasticsearch 2.3.0 on a Linux server.

Kibana appears to be running fine but upon running the command.

netstat -anp | grep 9200

I constantly see between 85-93 tcp to port 9200 in TIME_WAIT the port numbers being called are constantly changing.
Sample below:
tcp 0 0 127.0.0.1:58040 127.0.0.1:9200 TIME_WAIT -
tcp 0 0 127.0.0.1:58030 127.0.0.1:9200 TIME_WAIT -
tcp 0 0 127.0.0.1:57986 127.0.0.1:9200 TIME_WAIT -
tcp 0 0 127.0.0.1:57984 127.0.0.1:9200 TIME_WAIT -
tcp 0 0 127.0.0.1:58014 127.0.0.1:9200 TIME_WAIT -
tcp 0 0 127.0.0.1:57996 127.0.0.1:9200 TIME_WAIT -
tcp 0 0 127.0.0.1:58028 127.0.0.1:9200 TIME_WAIT -
tcp 0 0 127.0.0.1:57894 127.0.0.1:9200 TIME_WAIT -

Is this expected behavior or is their something wrong with my configuration i am using all the default settings in the kibana.yml file

Thanks in advance

Hi Chris,

I think it's OK. I just checked mine and I don't have that many right now, but I don't think you have a problem unless your system hits a limit on the number of open file descriptors.
