Hello folks,
i have a realy strange and annyoing problem here.
I have a very busy webserver. Around 2 weeks ago i upgraded from 2.2.18 to 2.4.2-ac20
(SCSI-System, 512 MB RAM, 3 SCSI-Disks, P-III-500). Everything worked fine, the 2.4x
Kernel
boosted the box a lot :)
But suddenly the box was offline. One technical assistant from our ISP tried to reboot
our server (he couldn't tell me if there had been any messages on the screen), but the
system always hangs on
Freeing unused kernel memory: xxk freed
So we took the box home and tried to boot it from a bootdisk (generated as we
installed the box,
redhat 7.0). The SAME problem occurs ...
Freeing unused kernel memory: xxk freed
The system hangs (i've tried 2.2.18 AND 2.4.2-ac20, 2.2.16 is on our bootdisk). I
thought
it could be the swap-partition ... so we inserted an IDE Disk, installed a small
system so that
i was able to mount the SCSI-Disks. So i rebuild the swap-parition with
mkswap /dev/sda5 and activated it via swapon /dev/sda5 ... worked.
So i tried to boot it again from the SCSI-Disks ... nothing! The same odd failure ...
I've never hat such Problems before .. we've already changed every piece of hardware
that's been in the
box (except the disks, but theire looking ok because i can mount them and run e2fsck
over it :) )
I need help, because we're already down for 3 Days now. What causes the system to hang
at this point??
What must i do the be able to boot the system from the scsi-disks again?
Thanx a lot,
Thomas
