The thing to do is find out the cause of the crash, which may well be
easier said than done. Is it a certain application, or does the entire
OS melt?

That looks fine to me. Might be worth monitoring the free values as
usage varies, so you can get some kind of idea of how it changes as
different numbers of people are using the system, but it doesn't look
like memory issues to me.
