Thanks Keith. The issue is not whether DPDK is using poll or select on the fd’s. The issue is that DPDK is raising the per-process number of fd’s above the maximum that glibc supports for select(). Therefore no other code within that process can reliably use select() on an fd set, because any file that is opened may get an fd number > 1024.
