Command-Z shortcut (Undo) suffers fatigue

AICC 2017 21.1.0

Mac OS Sierra 10.12.6

16 GB DDR3

Wondering if the Undo shortcut has ever gone lame for anyone else using my setup while working on a relatively (but not overly) complex file. After 45 to 60 minutes in a 20-40MB file with multiple Effects or detailed brushes or free form shapes with lots of points, the keyboard shortcut will become unresponsive, BUT the Edit>Undo command will remain fully functional. Saving, closing and reopening the same file will restore the shortcut to full potency for awhile.

Has anyone experienced it? Does anyone know the possible cause(s)? Has anyone been able to restore the keyboard shortcut in circumstances like this?

Thanks in advance.

    I'm almost sure that I saw that behaviour in the past a couple of times. As far as I can remember those files contained a lot of insanely complex appearance attributes.

    As they were probably just some of my experimental games to see how far one can go until the poor software gets overstressed, I did not try to find out possible reasons. Nor did I found a general solution.

    Well, no good answer, I guess.

    Old post, but, YES. This just happened to me in CC 2015.3 (El Capitan). If I reverted to "Default" Keyboard Shortcuts it started working again. Then I went back to my custom shortcut set, deleted the Cmd+Z already in "Undo" and re-assigned it. It started working again.

    Maybe not a "good" answer but very likely the correct one.

    I admit that I rather don't like the "correct answer" decoration because "correct" often means "altogether wrong" or factoidal in this forum.

    My nonbinding guess is that it is rather an ordinary RAM issue or – and that would be commendable – some kind of emergency plan is included in the general Illustrator code to prevent an application crash just because an Undo may cause it for whatever reason.
