- Tue Mar 15, 2016 9:07 am #43199 I had this on Arduino ESP ,, that turned out to be a simple syntax error / or left something out in a function...
Unfortunately I don't remember what it was....

In LUA I've seen this intermittantly with tight memory......

- Tue Mar 15, 2016 9:17 am #43200 Isn't that essentially a CRASH report.

I have seen something similar when my ESP module runs out of memory.
It spits out all this data then reboots.
I have never tried to interpret it... just thought it was similar to windows Blue Screen of Death (BSOD)

This is beneficial in debugging. (Your code or the interpreters)

Also if you are printing a lot of things you may wish to do a CLS to clear the browser output buffer.
