lrmd (heartbeat) is continuously pinging the default gateway

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 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.

Hm... Can you see in the

ps aux
output what process is pinging your gateway?

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

And if you don't know, nodody will :mad:, but thanks again. I will buy and read the german Oreilly book about heartbeat.
