One of my Org files hangs Emacs

One of my Org files hangs Emacs

[Marcin Borkowski]

Hi fellow Orgers,

so I have a bunch of Org files, most of them pretty big (over 1
megabyte), and one of them repeatedly causes my Emacsa to hang.
Sometimes a plain `C-g' helps, sometimes I need to kill the Emacs
process.  How do I even begin to find out what happens?  Any hints?

TIA,

1. Set debug-on-quit to t and study the backtrace you get after C-g
2. Set debug-on-error to t, send SIGUSR2 signal to Emacs and study the backtrace
3. Run emacs -Q only loading the Org version you use and try to
   reproduce. If you can, this is a bug in Org. If you can't, bisect
   your config to identify the cause (there is a helper bug-hunter
   package to assist; it can be used for manual reproduction as well)

I would suggest disabling "org persist" which has caused so much grief for me.

(setq org-element-cache-persistent nil)

Prior to me adding above line, I would get mysterious hangs, and all
kinds of frequent errors.  I tried debug-on-quit and debug-on-error, but
this "org persist" thing was impossible to debug.

org-persist can only affect opening and closing the file. I doubt that
it is the culprit here.

Note the most users do not experience such problems. Could you file a
separate bug report describing your situation in more details? We can
then try to work something out.

Did it happen for remote files opened via TRAMP?
