Hi Expert,
We are testing a new NVME disk. In the worst case, the DMA feedback duration of the NVME disk may reach seconds. In this case, I consider that if the process exits abnormally during the DMA transfer process, After another process restarts, it applies for the memory that is not finished. As a result, memory overrun may occur. However, DPDK and SPDK do not handle this problem. I would like to ask how the spdk is considered in this case?
Any feedbacks are welcome!
Brs
