Has anyone experienced this issue? More importantly, is it a problem? We  
haven't seen anything bad ... but just in case this is an indicator.

- We are running 3 dedicated masters (Machine:4GB JVM:2GB CPU:2)
- Cluster
  - 3 masters
  - 4 data nodes
  - 2 tribe nodes
  - 9 logstash client nodes

- The 1 extra thing we're doing is curling every 10 min to "\_nodes/stats"  
and "\_cat/indices" (about 3K indices).
- Relevant issues regarding management threadpool:
  - [https://github.com/elastic/elasticsearch/issues/7318](https://github.com/elastic/elasticsearch/issues/7318)
  - [https://github.com/elastic/elasticsearch/issues/7916](https://github.com/elastic/elasticsearch/issues/7916)

Thanks in advance!

Gavin
