I have experimented with it several times, but could not reproduce the problem.
In the past few months, I did see occasional failures of HOL-Nominal-Examples
due to resource problems, when many build jobs run in parallel (but not such
"hangs"). In such situations, I just ran it again and it usually worked.

Does "isabelle build pide_session=false" make a difference.
Did you use option -N?
What is your value for option -j and -o threads?

I still need to revisit a few pending aspects of this seemingly trivial
upgrade of isabelle build.
