Description

We should add some monitoring that allows us to track "old" node states, which potentially block revision gc.

Possible approaches:

• Add monitoring too old revisions (root node states) along with the stack traces from where they have been acquired.

• Include RecordId of root node state in the SessionMBean.

• Add additional tooling on top of the SessionMBean to make it easier to make sense of the wealth of information provided.
