For me, it does not happen with the agenda but when editing documents
(in org).  I can find no predictability to the hangs, however.  Some
days it happens more than once but I can also go many days without it
happening.

Emacs does not get completely hung in that it attempts to respond to C-g
(visual-bell indication happens).

The cache may be involved.  I do tend to have quite long and complicated
documents (full journal papers or a whole semester's set of slides for
one of my courses) with lots of babel src blocks, tables, inline tasks,
...

Anyway, not a deal breaker!
