Great. In the jira, be clear that you're reporting the mvel problem, not 
the planner score corruption.
Once the mvel problem is fixed, we can start looking at the planner 
score corruption, if it's still there (and isn't caused by the mvel 
problem).

Sounds like a memory leak (= serious issue), which has normally 
unrelated to score corruption.
