As a result, the buffer is out there doing nothing while a > potentially long-running async operation is being processed. In case of many > clients and many active requests, we'll have a lot of buffers allocated for > no reason. > Additionally, it is not always possible to ensure buffer release. Some > operations may never complete due to bugs, node restarts, etc, causing buffer > leaks. > To improve the situation: > * Release the request buffer as soon as reading is finished > * Allocate the response buffer only when the result is ready to write -- This message was sent by Atlassian Jira (v8.20.10#820010)
