Hm. What kind of sound does a busy CPU make? :-) > How do I find out what the problem is? (Never had any > before.) Yeah, attach a console and find out whats going on. > FreeBSD has always managed the highest loads, even > on normal PC hardware. Is it possible to bring the server > back without rebooting? I would lose a lot of unsaved data if > I had to reboot. I'm running 4.8-STABLE. When a server responds to ping, but ssh times out etc it often relates to hdd problems. Atleast in my experiences it has been so (dead disk). And if it is hdd problems, and FreeBSD couldnt get the disk to wake up again, you probably already have lost data. > Any help would be greatly appreciated. > Daniela
