Hello,

Lately (at least as of last 3 days), I have seen that when I try to
quit emacs, it gets stuck on one of my Org files; it's a personal
journal.org that I frequently update using org-capture. So that file
is usually open in one of the buffers.

Today I did M-x toggle-debug-on-quit and tried to quit emacs. When it
got stuck, I hit C-g and I saw this backtrace:

I had also enabled the profiler. The profiler report showed this:

I was able to quit emacs once I disabled the cache feature by setting
org-element-use-cache to nil.

Thanks for the report!

Could you try running M-: (org-element-at-point (point-max)) in your
journal.org and let me know if it takes a very long time?

Best,
Ihor
