IDE "Send to Espruino" stops working--size limit exceeded?

Sun 2021.10.10

'I've noticed that after a while . . . '

@TTBangler  Approx how many upload attempts?

'the Web IDE stops working'

What version of IDE and is the online one in use or the native app?

Please post process.env for current flashed version please.

'I'm seeing this with a 250 line, ~8k file'

FWIW I have been successful at over a 30K ~1000+ line file (which would minimize to 9K with comments removed) upload to a Pico. While doing this I kept an eye on available memory.

process.memory()

Once Free memory started getting below 150 JSVars, I would experience similar issues. I don't have a Bangle handy to check available memory, would you also post that. Were you checking free memory as left hand console snippets were uploaded?
