I saw this problem some time ago with an Oracle RAC guest. It haven't set the CP SET RUN ON, and as soon as the client issued some #CP Q SOMETHING, the server froze down, and linux rebooted. Looks like Oracle RAC have some kind of watchdog, and as CP MODE stops running Linux kernel for a little moment, the watchdog thinks the system froze down, and reboots the system. Setting RUN ON solved the problem. You can try this, it won't hurt, and I think RUN ON should be the default.
