On garbage collector stat I see strange situation - too many cases Full GC, below Full GC on 2 hrs 24 min 10 sec
Full GC stats
| Full GC Count | 12328 |

| Full GC reclaimed | 7.81 gb |
| Full GC total time | 40 sec 782 ms |

| Full GC avg time std dev | 2.60 ms |
| Full GC min/max time | 0.466 ms / 15.6 ms |
| Full GC Interval avg | 701 ms |
It's okey? Looks very strange. I have no see any other problem, elasticsearch log without errors / warnings / causes, response time - search time - index time no any problems, CPU usage on any node 20-30%, each node on deducated server.
