    Description

      We're running Jenkins on an Ubuntu-12.10 virtual machine, with two quad-core CPUs and 16GB RAM.

      This instance has 66 slaves, and around 80 jobs.
      Our instance is pretty much on 100% on one CPU, and the thread count dump keeps going up.

      Attaching the graphs from the monitoring plug-in, and a thread dump
      Any help on debugging this would be appreciated
