- I have had the same experience several times on both a HP425 and HP730.
- Each time the problem is corrected by turning off the optimization.
- Providing additional disk space makes no difference.

- I would hazard a guess that the optimizer is stuck in a perpetual cycle
- while tree-walking (a DAG is not a tree is not a DAG).
