TM4C129XNCZAD: Connecting multiple clients sending periodic HTTP requests to web server hosted on Tiva C results in net::ERR_CONNECTION_REFUSED

Part Number: TM4C129XNCZAD

Hello,

I am trying to run a web server hosted on a TM4C129XNCZAD board where the web client sends periodic HTTP requests every 5 seconds to the server.

I used the attached TI example and made a few modifications:
- Recommended heap size: 22528
- dchild task size: 4096
- Configure static IP
- Web Client sends periodic requests every 5 seconds and the server responds with some JSON formatted data


The issue I am running into is that after a while from connecting 2 web clients or more, I get the following error in the browser's dev tools console : net::ERR_CONNECTION_REFUSED.
The web server becomes inaccessible after getting that error and the only way to restore the connection is to reset the server.

You will find the zipped demo code and screenshots for the Error present in the browser's console and detailed ROV content attached, please check them for further details.

Thanks,
