Hi My issue was solved by updating the firmware on our Broadcom BCM57504 NIC (buggy firmware was 23.11.16.22). I also had to add the following option via ethtool for the NICs that were serving the bond: --offload eno12419np2 gro off --offload eno12429np3 gro off . This completely solved my problems. Maybe this can be relevant for your issue too.
