Hi, We have a solrcloud setup with 2 solr nodes and 3 ZK instances. Until recently I had my application server always call one of the solr nodes (via solrJ), and it worked just fine.
In order to improve reliability I put an Nginx reverse-proxy load balancer between my application server and the solr nodes. The response time remained almost the same but we started getting the msg: IOException occured when talking to server http://myserver.... every minute or so (very randomly but consistently). Since our code will just try again after a few milliseconds, the overall system continues to work fine, despite the delay. I tried increasing all nginx related timeout's to no avail. I've searched for this msg a lot and most replies seem to be related to ssl. We are using http2solrclient but no ssl to solr. Can anyone shed any light on this? Thanks! Reinaldo
