Could you give an idea about the number of repositories you have configured for your jobs, how many modules in each repository, and how many files in each module? This will have a significant bearing on the size of the change records we hold.
Thanks.

MavenModuleSetBuild -> CopyOnWriteArrayList -> CvsRevisionState
can be set to null?

A heap dump is showing 126 instances of CvsRevisionState taking up 840 MB of heap memory.... this seems rather high...
