generic/551 sometimes fails because it's killed by OOM killer. That is because aio-dio-write-verify, which is called by generic/551, tries to allocate memory even though the total allocation size exceeds the available memory. aio-dio-write-verify allocates memory according to the 'size' argument, and generic/551 passes the argument. Stop adding the argument when the total size is exceeds the available memory.
