And just now, I rebuild another verion 6.1-RELEASE-p11. The system crashed again within one hour. I'd like to try to use Uni-Processor mode to try again. Any one know how to set the system to one processor without recompile kernel or remove hardware? -- Ma Jie 2006/12/19, Stephen Montgomery-Smith : > > Joe Holden wrote: > > Ma wrote: > > > >> I have almost the same reboots on my server. :( And it may reboot > >> serval times a day.
