Expected behavior
Multiple consecutive HTTP GET requests to a httpserver running on a NodeMCU do not cause the platform to OOM and crash.
Actual behavior
Multiple consecutive HTTP GET requests to a httpserver running on a NodeMCU cause crash.
Test code
Provide a Minimal, Complete, and Verifiable example which will reproduce the problem.
station_cfg={}
station_cfg.ssid="..."
station_cfg.pwd="..."
station_cfg.auto=true
station_cfg.save=false
wifi.setmode(wifi.STATION)
wifi.sta.config(station_cfg)
print(wifi.sta.getip())
require("httpserver").createServer(80, function(req, res)
res:finish("Error", 500)
end)
After uploading this code issue 100 GET requests (one after another) to the so created server.
