A too-long file of seemingly ANY type will freeze Pluma as it tries to load all of it into RAM, this has been around w while. Note that this has been fixed in Gedit, in fact this (as well as Gedit having an "edit anyway" force open option when invalid characters are detected) are why I keep Gedit installed, for file Pluma chokes on. This means there should be commits to gedit for both of these that could be backported to Pluma, and would fix some real usablity issues

odd when I check the system monitor while trying to open the file - I still have 6GB of RAM free, only one CPU core is maxed out.

I don't think its a matter of running out of RAM but rather a matter of mishandling loading large files

The same thing happened to me with a .json file, and I assumed it was due to the file being too large, until I opened a .SQL of the same size with pluma and it didn't freeze.
Indeed, with a 1.3 mb .json file, puma pluma freezes up completely. It's not an inherited issue or GTK related since with gedit using MATE it doesn't occur.
