I doubt that was the main datastore. It might have been a configuration database though, which I can see it being an issue given that it sounds like it was business logic causing the issues.

It was. The way they built it out was UML > generated Java, which persisted data as XML. The MarkLogic database could then do xpath/queries (think stored procedures) for the Java layer - so not just POJO > XML, though there was some of that too. It ended up being a non-trivial cluster.

Your explanation made me dry-heave. UML > Java generation explains why their deployments seemed to contain obscene amounts of code that no one understood.
