I know is positive since I've added a print in my code to test that.. I've a strange issue where once I extract N items from the pool (where N is the exact size of the pool) then the rte_mempool_get fails even if in between the N extraction I've replenished the pool with rte_mempool_put so that rte_mempool_avail_count is always positive. The pool is created like this: data_pool_ = rte_mempool_create( fdo_str_name, config_->chunk_count, chunk_size, 0, // cache_size 0, // private_data_size nullptr, // mp_init nullptr, // mp_init_arg nullptr, // obj_init nullptr, // obj_init_arg config_->host_socket_id, 0 ); Producer and consumer are running on separate threads, but that should not be the issue since the creation flag is 0 (Multi producer/Multi consumer). So in my scenario is chunk_count is say 128, then after 128 GET operations I get null even if I PUT back 128 items before this last GET (and again, rte_mempool_avail_count is 128...) Is weird, since this is happening since I've upgraded to 21.02 from 20.02.1, may I have messed up the compilation of the new DPDK? How can I investigate this issue?
