Colleagues,

I am working on esp32 WROOM module to interact with a rest API using Arduino 1.8.19 . I am using AsyncHTTP to send the GET message.
My code is working, but randomly, the system crashes always on "tcp_update_rcv_ann_wnd"

This is part of my debug code and it crashes on the callback function, always after state 3 , that means still receiving data
( readyStateLoading = 3, // receiving, partial data available)

callback -4 NOT_CONNECTED 4estado_entrando 5
callback -4 NOT_CONNECTED 1estado_entrando 5
callback 200 HTTP OK 2estado_entrando 5
callback 200 HTTP OK 3estado_entrando 5

assert failed: tcp_update_rcv_ann_wnd IDF/components/lwip/lwip/src/core/tcp.c:951 (new_rcv_ann_wnd <= 0xffff)

My callback function is the same as in the AsyncHTTP .
void requestCB(void *optParm, AsyncHTTPRequest *request, int readyState)
{
(void) optParm;
String aux;
int i,k,comienzo_array,fin_array,comienzo_resultado;
Serial.print("callback ");
Serial.print(request->responseHTTPcode());
Serial.print(" ");
Serial.print(request->responseHTTPString());
Serial.print(" ");
Serial.print(readyState);
Serial.print("estado_entrando ");
Serial.println(estado);
if (readyState == readyStateDone)
{
AHTTP_LOGDEBUG(F("\n**************************************"));
AHTTP_LOGDEBUG1(F("Response Code = "), request->responseHTTPString());

if (request->responseHTTPcode() == 200)
{
Serial.print("estado ");
Serial.println(estado);
if (estado==AWAITING_STATUS_ZONAS)
{
Serial.println(F("\n**************************************"));
.........

In the link below we can see the calling function and is related to the window size......

Any idea what might be wrong?

Did you solved your problem ?
