New != works

Another thought aside from bad hardware, since you mention this
happens after a number of days... what else has changed?

When you've run this in the past on older hardware, were you also
running an older version of Ubuntu or Zoneminder or any other
software?

How about running a simple script via cron every 5 minutes or so to
track mem usage across time via ps or something?  This also sounds
like a memory leak somewhere that slowly eats away your memory...

Another possibility is ambient temperature in the case, though that
usually causes problems a lot faster than "a few days" but if the fans
in the case are just slightly less efficient than they need to be, a
very slow buildup of heat could also be a culprit...

heh... this is a rabbit hole :)  but my money is on bad ram as was
suggested, or a memory leak in some program you're running.
