Default lrmd (heartbeat) is continuously pinging the default gateway

Hi,

I have a 2 node heartbeat cluster. The network admin told me that gets 20 ping request per second on the gateway from the active node. By looking on the node it's seems like lrmd is pinging the gateway. Both nodes are in the same network, so the gateway should not be used by heartbeat.

The ping function in hs.cf is not enabled. Does everyone know where it can come from? I don't even understand why 20 times per second, as the keepalive is set to 1 second.

I'm a little bit lost, as I don't really know what's happening, So any help is appreciated.

Thanks

I do not have access to the machine right now, but the command was something like ping -c1 -q -n MY_GATEWAY_IP, the PPID was lrmd.

Thanks falko
