Hi, please help.
Do exist test case which are used curl and /nodes/stats response
for issue
Ensure that releasing listener is called ?
I have exception

and I would like detect rootcause of this exception before elasticsearch upgrade.
Also can you please explain the difference between
limit_size and estimated_size fields? I could not find it in documentation
