Packet Drop on 40G Interface

Murilo MoraisDec 8 2022

Good morning everyone!
I've been using Oracle Linux 8.x for less than a year, so far it's meeting all my needs and everything is working fine. I'm using it primarily for virtualization with OLVM (oVirt) and storage with CEPH.
My problem is in the networking part, because I'm noticing a packet drop where there shouldn't be.
I'm using 40G Intel cards in 5 machines with CEPH, when the traffic increases to around 1Gbps I notice that the interface DROP counter also increases, but I don't notice service interruption.
With relatively low traffic there shouldn't be these drops, am I correct? Could there be another variable that is driving this behavior?
