Hello Hamaguchi-san,<br>
<br>
Do you get same result by executing the command manually with<br>
different parameters like this?<br>
#/usr/libexec/heartbeat/send_a<wbr>rp -i 1500 -r 8 -p<br>
/var/run/resource-agents/send_<wbr>arp-192.168.12.215 eth0 192.168.12.215<br>
auto not_used not_used<br>
<br>
Please also make sure the PID file has been created properly.<br>
<br>
Thank you,<br>
<br>
Takehiro MATSUSHIMA<br>
