occasional HardFault on esp32-s3 with httpserver

[jepler]

CircuitPython version

Adafruit CircuitPython 9.0.0-alpha.2-13-gdc5845fa41 on 2023-11-04; Adafruit Camera with ESP32S3

Code/REPL

# I do not have a minimized standalone program that reproduces the problem

Behavior

You are in safe mode because:
CircuitPython core code crashed hard. Whoops!
Hard fault: memory access or instruction error.
Please file an issue with your program at github.com/adafruit/circuitpython/issues.
Press reset to exit safe mode.

Description

The camera itself is stable, it's only since adding use of wifi & httpserver to my program that this has started occurring.

Additional information

yes I know this is an old version of circuitpython and I should try a current one

I have seem multiple reports of hard-fault with httpserver, although none with clear indication of what might be causing them.

If I may suggest one thing, please try setting the poll_interval on serve_forever() or add time.sleep() between calling .poll().

Even better would be making it a async function with asyncio.sleep() and running the program like in this example

When I was trying to find a reason for hard-faults, it seemed like it helped with stability of the server.

I'm going to close this because there hasn't been any specific reproducing code added. Feel free to file another issue if it crops up again.
