Hi
I use heartbeat 2.0.7 from openSuSE 10.2
10.250.250.27 is master
10.250.250.28 is backup
They are connected with direct ethernet cable
When watching UDP heartbeats with tshark, my master machine says this
(checksum errors):
16:27:24.140509 10.250.250.28 -> 10.250.250.27 UDP Source port: 32779

My backup machine says this (no checksum errors):

When backup becomes master, this situation does not change, so is not
dependant on master/backup status.
master and backup are identical hardware, both use openSuSE 10.2, Intel
Primergy RX300 and Dell 82541GI/PI Gigabit Ethernet controllers.
I tried using ucast and bcast heartbeats, both show checksum errors from
master machine.
Is this something to worry about and what can be done about it?

Dominik
