CPU Spinning when there is an RST packet while serving the response [MI 4.x.x]

[Sumudu-Sahan]

When the backend sends an RST packet while writing the response to the opened HTTP connection thread, the Sender I/O dispatcher thread will spin, and hence, the high CPU behavior will be observed.

Reproducing Steps

• Download the attached BE and start it.
• Deploy a sample API by pointing to the deployed HTTP backend.
• Invoke the API.

curl --location 'https://localhost:8253/test' -H 'Content-Type: application/xml' -d '<?xml version="1.0"?>
<catalog>
</catalog>' -kv

• Check the CPU usage and able to see the 100% usage after the invocation.
