Q: Mac Server showing 0 memory usage, 0 network traffic and constantly rising CPU usage
Hello,
I use my 2011 Mac Mini as a server, running Mountain Lion and Lion Server. At about 5AM this morning my memory usage went from a constant 1.6GB usage instantly down to 0 (zero)GB, at the same time my processor usage went to 0 and rose linearly thereafter. My network usage also went to 0. This isn't new, this has happened for the last month, about %85 of the time I leave my computer for more than a few hours. Of course my first assumption is that I have some kind of memory leak or uncaught fatal error. What are the first steps I should take to get to the bottom of the problem?
The Mac Mini auto-sleeps after 15 minutes.
Services enabled: ftp, sftp, ssh, websites, file sharing.
Here's the last few lines in the system log:

There is nothing noteworthy in any other logs.
The problem may or may not have started when I upgraded from Lion to Mountain Lion.
Please advise, standing by...
Mac mini, OS X Mountain Lion (10.8.3)
