Very often I get an error: Discover: Request Timeout after 60000ms. (I already increased the timeout)
This is very annoying and causes problems with users.
Ahead of Kibana is Apache, and I see such errors:
[Thu Jun 29 13:55:02.241580 2017] [proxy_http:error] [pid 10195] (20014)Internal error: [client 192.168.1.128:53462] AH01102: error reading status line from remote server localhost:5601, referer: https://elk.local/app/kibana

I have one server: 24 CPU, 64Gb RAM, SAS disks.
jvm for elasticsearch:
-Xms40g
-Xmx40g
90% of all request are go to one index - application-YYYY.MM.dd, 40 days/24 shards, one day = 20Gb.
Tell me where there can be a problem please. Thank you
