Bug description:
I'm running Ubuntu Trusty 14.04 on a new machine with 8GB of RAM, and
it seems to be locking up periodically and nothing is in syslog file.
I've installed Nagios and have been watching the graphs, and it looks
like memory is going high from 7% to 72% in just a span of 10 mins.
Only node process are running on server. In top I found all process
are running very normal memory consumption. Even after stopping node
process. Memory remains with same utilization.
free agrees, claiming I'm using more than 5.7G of memory:

However, I'm having trouble determining what exactly is eating all of that
memory. Running top or htop doesn't seem to single anything out, and ps_mem.py
(https://raw.github.com/pixelb/ps_mem/master/ps_mem.py) claims that I'm using

This might be better suited for AskUbuntu or the Ubuntu forum.
It looks like the buffers/cache is the cause. Please attach boot logs
(kern.log/syslog) to help us see what is going.
