Can I ignore these E:M xxxx (yyyy blocks) messages?

#1

These E:M xxxx (yyyy blocks) messages appear after I grow the init.js script with more functions:

Can I just ignore them? Any hints, please?

Basically it means you are going out of memory (the system could not allocate 12865 bytes).

#3

But, after that, the firmware still functions. Can I ignore it?
