Memory Allocation
I was wondering if anyone can give me some advise
I have two servers with SoftLayer and they have installed Centos and CPanel for me.
Any advise on memory allocation, especially vmalloc as server #1 I received an error at time of bootup: allocation failed: out of vmalloc space - use vmalloc= to increase size
Server #1

It is not a virtual machine, it is 2 seperate dedicated servers running Centos. 0 -
Have you attempted to install any sort of virtualization on them at all? Also, can your host confirm that they are not "virtual dedicated's"? 0 -

They are full dedicated servers which I lease from SoftLayer. They have confirmed they are NOT Virtual Dedicated servers0 -
Fair enough. Have you followed the instructions yourself in the link I had provided? 0 -

Yes I did BUT: 1: LILO: I was not able to locate a file called: /etc/lilo.conf (did a full search for that file) 2: GRUB2: no file /etc/default/grub 3: GRUB: Found the file /boot/grub/menu.lst (see below) but there is no reference to vmalloc in it# grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file # NOTICE: You have a /boot partition. This means that # all kernel and initrd paths are relative to /boot/, eg. # root (hd0,0) # kernel /vmlinuz-version ro root=/dev/sda5 # initrd /initrd-version.img #boot=/dev/sda default=0 timeout=5 splashimage=(hd0,0)/grub/splash.xpm.gz hiddenmenu title CentOS (2.6.18-404.el5PAE) root (hd0,0) kernel /vmlinuz-2.6.18-404.el5PAE ro root=LABEL=/ initrd /initrd-2.6.18-404.el5PAE.img title CentOS (2.6.18-398.el5PAE) root (hd0,0) kernel /vmlinuz-2.6.18-398.el5PAE ro root=LABEL=/ initrd /initrd-2.6.18-398.el5PAE.img0 -
But isn't that for Fedora and not Centos? 0 -
It is. However, I personally tend to watch both of them as they are "relatively" similar in regards to grub. 0 -
Frustrating as that quoted issue seemed to be with grub 0.95 and fixed in 0.96 AND I am running 0.97 0 -
My apologies. I was unaware as to which version you were on. 0
