Reason: ======= Race condition between btr_search_drop_hash_index() and btr_search_lazy_free(). One thread does resizing of buffer pool and clears the ahi on all pages in the buffer pool, frees the index and table while removing the last reference. At the same time, other thread access index->heap in btr_search_drop_hash_index(). Solution: ========= Acquire the respective ahi latch before checking index->freed() btr_search_drop_page_hash_index(): Added new parameter to indicate that drop ahi entries only if the index is marked as freed btr_search_check_marked_free_index(): Acquire all ahi latches and return true if the index was freed |
