If the hash table created with RTE_HASH_EXTRA_FLAGS_MULTI_WRITER_ADD extra flags, and more one worker add same value and same key. the firt worker will add value & key success, and second worker will execute lock and found a exist value & key and return exist index without unlock. then it course next adder spinlock deadlock!
Best Regards!
