RE: sql identity column generate always (WHY HAVE TO RESET)

I believe there are SQL options to copy a table instead of using CPYF which will do a better job of maintaining the identity column. See INCLUDING IDENTITY COLUMN ATTRIBUTES at

CPYF probably - it will keep ID from from_file and not increment ID in to-file

We all know that sometimes the identity column gets "out of whack" and
that we have to reset it with the alter/restart...

My question is why does it get out of whack.
Even better question, how can we detect the presence of the out of
whackness before we are faced with a "attempt to write duplicate"
because it was "out of whack"?
Is there a system table we can query to look at to detect these time bombs?

Abused google looking for an answer and everyone prides themselves
with how to restart it... and never is it explained how to detect them beforehand.

TIA
