Please verify your components have been updated correctly. Keep in mind that in terms of threading: OPAL_FREE_LIST_GET -> opal_free_list_get_st OPAL_FREE_LIST_RETURN -> opal_free_list_return_st I used the opal_using_threads() variant anytime it appeared multiple threads could be operating on the free list. If this is not the case update to _st. If multiple threads are always in use change to _mt.
