Symptoms
"Error, some other host already uses address IP_ADDRESS" error on command line on Linux-based host when restarting the "network" service (with "service network restart" command) on a host, or when rebooting a host.
"Found duplicate IP address IP_ADDRESS" error on Windows-based host when restarting the "Network Connections" or "Server" service on a host, or when rebooting a host.
Cause
There are two causes:
ClusterXL answers the Gratuitous ARP Requests (sent by hosts on the network) for IP addresses configured in the $FWDIR/conf/local.arp file (per sk30197).
ClusterXL with VMAC (per sk50840) sends Gratuitous ARP Requests for IP addresses configured in the $FWDIR/conf/local.arp file (per sk30197).
