why would I spawn child cursors with different execution plans for the exact same query with bind variables with the same plan_hash_value?

I forgot to mention - there could also be different explain plans for different child cursors of the same hash_value - check the "child_number" column, and then check v$sql_shared_cursor to get an idea of why there are multiple children.

It's normal to have multiple rows in v$sql_plan for a given hash_value - each row represents a single step of the explain plan. Do both rows have the same plan_hash_value?
