Matabase throws 502 randomly


We have been facing this issues from quiet sometime now, metabase starts throwing 502’s randomly. We neither find error logs. Is there anything we are missing.?

The only error being :slight_smile:
2018/02/20 05:04:01 [error] 4002#0: *2660 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: x.x.x.x, server: , request: “GET /api/health HTTP/1.1”, upstream: “http://x.x.x.x:3000/api/health”, host: “x.x.x.x”

Please help.
