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

It's perhaps not the real issue or not the only issue, but you have 4 threads running "deflateBytes", for org.kohsuke.stapler.compression.CompressionFilter.reportException.
1) Do you still have threads running "deflateBytes" in a new thread dump?
2) What version of Jenkins are you using? (Is it Jenkins v1.520 or later?)
