Can't answer for sure since you didn't provide code, but I have come across similar error before.

Planner tool (not to be confused with physical/logical plans) is NOT thread safe. Even if you're calling reset(), it's likely that you are trying to use the same Planner from different threads. Instead of doing this, just instantiate a new Planner for each query. Way less headache.
