I had to increase number of TCP connections as well. Chrome will do
several connections to speed up web page loading, not that it does on

We found that the issue was only occuring when the browser used is chrome
and not evident while testing with Firefox browser or wget from a linux pc.
Also we were using netconn_listen() for web server. Note that our webserver

What can be the reason of using additional custom pools? Is it about
preparing memory for copying data from PBUF_POOL_base for a
