F767ZI+FreeRTOS+lwip can't support more than 2 clients?

I require to run 3 clients. I start 3 lwip threads using sys_thread_new. Each thread will service 3 python clients via 3 distinct Ports. Everything seems to be working when running only 2 threads . However, when a third client is added things become weird. Only one client is able to connect . When a second or third client tries to connect, it returns connection reset by peer.

Asking if you're using HTTP and/or HTTPS.

I'm throwing guesses.

MEMP_NUM_TCP_PCB?

Lots of information on the web about lwIP.

Search https://lists.nongnu.org/mailman/listinfo/lwip-users too.
