Dear Dag, Thank you for your answer.
I checked the VR log(/var/log/kern.log). It shows that the VR had been out of memory, and OOMKiller on VR occurred to stop apache2 & dnsmasq service. Do you have a such experience(out of memory on the VR)? Regards ************************************************** Ryota Maruko Hitachi Solusions East Japan,Ltd.
