Hi, I have fixed the problem now. It was due to the fact that we now tag samples with pid/tid when they are added to hash table. But in aggregation, you want to ignore pid/tid. So the patch makes pid/tid anonymous. Also found a serialization problem.
Pull pfmon from CVS and try again. Let me know if it works. Thanks.
