Problem Description

I get the following error when I run a fairly heavy duty network application that is simultaneously acting as an HTTP server and HTTP client when connecting a browser.

W (338406) wifi: mem fail :
W (338466) wifi: alloc eb len=24 type=3 fail, heap:4140676

After the above failure, I tried several configurations and they all failed.

I also expected the the ESP32-WROVER-B to be able to do many TCP connections, but I noticed that I can only configure up to 16 connections using make menuconfig.

Do you have plans on supporting more connections? I would like to run up to 100 full duplex TCP connections.
