So thanks to those who helped me resolve this.  
In the end it turned out to be apache-ssl process's using something in /var to lock.  
To resolve it I ran lsof (a very useful tool) and piped it through grep for the /var entries, this showed that apache-ssl was slowly filling up /var.

I just did a restart and the disk usage went back to 1%.
