ChenXi updated RATIS-2213:
--------------------------
Description:
h2. Phenomenon
During our online test of Streaming writing, we found some memory leaks. When a
DN write traffic exceeds 1GB/s ~ 2GB/s, Netty's Direct memory will continue to
grow.
h2. Version
Ozone-1.4.1 based internal build, use the Ratis version 3.1.1
h2. Reproduce Way
I found two ways to reproduce the DataStreamMapImpl#
map and DataStreamManagement#streams leaks.
For the detail we can refer to https://issues.apache.org/jira/browse/HDDS-11939
h2. screenshot
Direct memory increase

This is a mat analysis of a memory dump of a DN long after it has stopped
writing.
