Hi, We had intermittent connectivity loss with Intel X710 network adapters on some kernel versions (especially the newest Centos kernels). We worked around it by installing ElRepo kernels. Guess RHEL is a bit too conservative adopting bug fixes. Perhaps you could try it too; at least it might help to pinpoint the cause.
