Welcome to our community! :smiley:

What is the output from the _cluster/stats?pretty&human API?

Thank you for your reply :laughing:，i can't get the stats of that moment now and do you want current stats？which part do you need？
And i found that moment an index has both write and search tasks ，Is that a problem？

We need to see the whole thing please.

You have a pretty large cluster there!

What is the output from _cat/threadpools?v and hot threads when you get these rejections?

You should upgrade, 7.10 is relatively old and latest is 7.14.

From grafana i can see active and pool is not full but rejected happened。i'm sorry for i can‘t get hot thread info in that moment。 and is there some thing can cause this problem？
