aging, hardware can sometimes need such a reboot compromise for

Maybe all the "nice" clusters out there never have this issue but for
me it is fairly common. Just confessing.
Why, exactly, are you assuming that your freezes are one-off random
errors due to aging hardware? Sounds like you're either guessing, or
you _are_ doing forensics, but aren't calling it forensics.
*MY* aging hardware usually just falls over dead when it's done with its
useful life. Too many intermittent errors/failures causes me to do
sufficient diagnostics to repair the node (if it's cheap and easy
enough) or drop it in the latest surplus run.
