I have a nodemcu esp-12e that is connected to a dallas ds18b20 onewire temperature sensor
reading the temperature from the sensor works as expected

commenting out that code, connecting the module to aws iot and publishing a message works as expected

when uncommenting the onewire libraries in init.js (api_arduino_{onewire,dallas_temp}.js) the module crashes with an exception (logs below)

is this a known issue?

Looks like OOM.
Could you log free RAM as well please?

I've gotten another interesting error message:
heap integrity broken: block links don't match: 3473 -> 3604, but 3604 -> 3328

i've attached two logs with free ram (timer at 100ms, just doing print Sys.free_ram())

err2.txt

looks like it's indeed free RAM. if i comment out all load statements besides sys, timer, onewire and dallas_temp it does succesfully connect.

looks like the initial mqtt connect takes about 11k of ram. do you have any tips on how to load libraries after that? if i add load statements later in the code, they don't seem to work (i get an error about not being able to read the file)

We need to restore mmap and JS pre-compile.
@dimonomid please handle!

@zendes , we've restored mmap on esp platform, this frees 5+ K of RAM. Please try now with the latest firmware (if you use release, you'll need to update to latest with mos update latest)

Will do. I'll get back to you in about a day with the results.

looks like that fixed it. i can now load all libs at the top, and publish a ds18b20 reading to aws iot without the device rebooting or crashing. thnx!
