Jstack was not that helpful for me, I'm simply not that familiar with using
the tool. Looking at the thread for the 'configure' request I see (here's a
stack snippet)

But in the logs, I noticed the following:
WARNING: Failed to resolve class
com.thoughtworks.xstream.mapper.CannotResolveClassException:
org.jenkinsci.plugins.envinject.EnvInjectPluginAction
at
com.thoughtworks.xstream.mapper.DefaultMapper.realClass(DefaultMapper.java:56)
So, I removed the use of the EnvInject plugin, uninstalled it and so far...
the spiking has disappeared. Course... the real test will be after many
hours of uptime.
