Based in this [comment](https://discuss.elastic.co/t/es5-indexing-performance-seems-slow/65084/3) these logs are normal, moreover i am getting few GC logs per hour, for example: at 8am:  
**Node-3:-----------------------**  
[2018-01-10T08:04:41,292][INFO][o.e.m.j.JvmGcMonitorService] [node-3] [gc][405989] overhead, spent [322ms] collecting in the last [1s]

**Node-4:-----------------------**  
[2018-01-10T08:50:00,775][INFO][o.e.m.j.JvmGcMonitorService] [node-4] [gc][409052] overhead, spent [252ms] collecting in the last [1s]

Questions:

1. do these logs evidence a bad configuration o cluster problem?
2. which relation have these logs and the cross cluster search queries?
