I opened a closed index with 5 shards. All of the shards allocated fine except 1. When I check the logs I see an error about too many open files.

```
[WARN][o.e.c.a.s.ShardStateAction] [bos1-es2] [px-web-server-2018.03.06][4] received shard failed for shard id [[px-web-server-2018.03.06][4]], allocation id [tVvJ\

```

I checked \_nodes/stats/process and it says that I have 65536 "max\_file\_descriptors" and "open\_file\_descriptors" is only 8271. What am I missing here?  
Thanks!

I think that you've been bitten by an endless flush bug that will be fixed in 6.2.4: [https://github.com/elastic/elasticsearch/pull/29125](https://github.com/elastic/elasticsearch/pull/29125)
