We're running into a memory leak that might be related to the jclouds plugin. Running with a heap of 5.5gb, old gen becomes full after a couple of days with moderate to heavy load.

We have a setup with jenkins & jclouds provisioning test instances on a private nova-compute cloud.

When I look at the heap dump it seems that there's a guava cache that occupies 70% of the heap. Any idea how to proceed debugging this?

This is jeknins 1.492, jclouds plugin 2.3.1
