I broke down my Jenkins trying to use this plugin. It turned out that plugin stores the entire coverage in XML format in build.xml file in jenkins (
{Jenkins}
JENKINS_HOME
/jobs/
{
[
Project
}
]
/builds/
{
[
Build
}
]
/build.xml). Boolean values about covered/uncovered lines stored there as XML tags with indentation for readability :)
<boolean>true</boolean>
Thus my 600K code coverage .exec bin file consumed more than 700M on the hard disk for the build.xml.
This is a half of the problem. Further Jenkins keeps all builds information including mentioned above build.xml in RAM. That's how I've caught OutOfMemory exceptions in Jenkins and got it broken.

For what it’s worth Kohsuke & I recently did some minor memory usage fixes in the Cobertura plugin, and I experimented with more: https://github.com/jenkinsci/cobertura-plugin/compare/master...trove

This issue makes the plugin forbidden to installation on JBoss Jenkins instance.
