One other approach would be to install something like munin that will monitor
resources, record their data, and allow you to review graphs showing metrics
over time.  That might highlight where the shortage is coming from.

I like munin, because it is trivial to add extra monitoring to, but there
are a wide range of solutions to this problem.
