Memory for crash kernel error message

DotHQ · 03-09-2009, 01:01 PM

I'm seeing the Memory for crash kernel error message and am aware of the tidbit below, saying it is safe to ignore. However, I was wondering if there is a kdump setting where you can assign a little memory to it to get rid of this message? Any ideas?

Does everyone just put up with the message, or is there a way to get rid of it?

One more try .... has anyone set kdump?

I haven't set kdump. I see that message from time to time when I reboot. You can close your eyes briefly to ignore the message. :P

The only time I see that message is when I reboot. Since I only have to reboot when there is kernel update, I just do not see it that often.

I thought someone had finally figured out a way to get rid of this annoying little blip.
Well, you made me smile.

If your not using Crash dumps then you can safely disable them. chkconfig kdump off and reboot for it to take effect.
If however do you need to enable crash dumps this means you enabled crash dumps but not setup a crash dump kernel memory area.
You will need to add a crashdump kernel param to the system startup (grub boot configuration)
