What Do I Expect To Happen?
I expect system to no drop network packets
What Happened Instead?
As you can see, server is dropping quite a few network packets.
Please let me know if you need any additional information.
NOTE: As a test, I installed 3 other machines (2 HP Server Class (DL380 and DL580) and One Laptop (Asus)) with similar installed software, but not from upgrade; fresh installed. All machines had same problem on br0 interface.
