How does this run out of ram in about 7-9 loops

[GM-Script-Writer-62850]

i thought i found a way to reproduce a bug so i started working on test code, i may have been successful, not sure

if i run out of ram during try: will the script halt without a error?

hardware: W5500-PICO-EVB

from machine import Pin
from time import sleep
from dht import DHT22
from threadsafe import Message # https://github.com/peterhinch/micropython-async/tree/master/v3/threadsafe
import _thread
import urequest # https://github.com/micropython/micropython-lib/issues/546
import network
import uasyncio
#from gc import collect

print("Hello World")

#hard reset sensor
Pin(7, Pin.OUT, value=0)
Pin(8, Pin.OUT, value=0)
sleep(1)

#setup sensor
Pin(7, Pin.OUT, value=1)#This pin powers the sensor
sleep(2)
sensor=DHT22(Pin(8))

LED=Pin(25, Pin.OUT)#debug LED (onboard)

nic=network.WIZNET5K()
nic.active(True)
err=1
while err:
	try:
		nic.ifconfig("dhcp")
		err=0
	except Exception as e:
		print("Network error:",e)
print(nic.ifconfig())

unblock_thread_lock=uasyncio.Lock()
async def unblock(func, *args, **kwargs):#https://github.com/peterhinch/micropython-async/blob/master/v3/docs/THREADING.md#4-taming-blocking-functions
	def wrap(func, message, args, kwargs):
		message.set(func(*args, **kwargs)) # Run the blocking function.
	msg = Message()
	await unblock_thread_lock.acquire()
	LED.on()
	_thread.start_new_thread(wrap, (func, msg, args, kwargs))
	msg=await msg
	LED.off()
	unblock_thread_lock.release()
	return msg

async def main():
	while True:
		await uasyncio.sleep(10)# simulate time for other stuff to work
		uasyncio.create_task(unblock(urequest.get,"http://10.0.0.69:8080/ok.txt")) # test page: 2 byte text file
		# just need url to be sent, do not care about a reply, just yolo it
		await uasyncio.sleep(10)# simulate time for other stuff to work
		await unblock(sensor.measure)
		print(sensor.temperature(),"C;",sensor.humidity(),"%")
		#uasyncio.create_task(unblock(collect))
		#collect()
uasyncio.run(main())

If you are afraid of running out of ram it may help to check that by e.g. introducing a print("Free RAM",gc.mem_free()) at several places in the code.
Can you ensure that all the threads and tasks that you create in every iteration (they consume RAM) are finished and the memory released? I would suggest testing that with e.g. the above.

the issue was i was not using .close() on the urequest response in that code

it is not a ram usage problem

it thought i had a fix and now i have been proven wrong yet again...

But you found that yourself, which is good....
