Http request fails with ENOMEM

[DonJayamanne]

Got an ESP32 (M5Stack), and making a simple Https request fails.
Tried soft reset and reboot.
Copied source from urequests and ran it manually with gc.collect at everypoint.
Still fell over at the same place.

Falls over when executing s = ussl.wrap_socket(s, server_hostname=host).
Bombs with Error 12, ENOMEM

Which firmware version are you using? How many concurrent HTTP requests are you doing and/or does it always fail on the first request or only on subsequent ones?

This is quite possibly related to #5303 , in which case you might have more luck with an IDF3 build, or a newer IDF4 build.

FYi, despite the ENOMEM error, the memory used by wrap_socket doesn't come from the MicroPython heap, which is why gc.collect() does not help.

Seems similar than #7038

This issue is now being tracked in #8940.
