Bypassing 3GB RAM Limit
Jul 23, 2008
My server has 8GB RAM, however processes are limited to 3GB it seems, even if most of the memory is free (I have a mathematical program that mmaps lots of files and needs more than 3GB). I read somewhere that this is because the OS is 32-bit, but that it could be bypassed with "hugemem" kernel support.
I doubt that my host would install this for me, so how can I do this myself without breaking my server I've never done anything like alter a Linux kernel. My current OS is:
Linux 2.6.9-67.0.20.ELsmp #1 SMP Wed Jun 18 12:40:47 EDT 2008 i686 i686 i386 GNU/Linux With WHM 11.2.0, cPanel 11.11.0-S16999, REDHAT Enterprise 4 i686 - WHM X v3.1.0.

I have a server with the following specs:
2 x Xeon 2.0 Ghz
4 x 2 Gb DDR RAM (8 Gb total)
I am trying many OS's but none of them worked as it should:
- Windows 2000: install aborted
- Windows XP: install aborted
- CentOS 4.4: install OK but Kernel panic on start-up
- CentOS 3.8: instal OK, only 3.8 Gb identified but the OS out of 8 Gb
- CentOS 3.8 64 bits: couldn't install, CPUs support only 32 bits
Add to this, the machine boots on EL Kernel on CentOS 4.4 but not on the SMP Kernel!
how I could run this machine on Linux with 8 Gb RAM?

I recently used these forums to help narrow my search for a reliable, competent host. I choose to avoid the larger hosts that sells unlimited or large amounts of disk space and bandwidth. I went with a smaller host that sells a 1GB disk space and 10GB bandwidth package that is reasonably priced. Keep in mind that my site is new and will likely only be visited by friends and family. I feel this package is appropriate for my needs.
Should I be concerned about a host that will suspend my site if I reach my limit? As a customer I would rather be notified to upgrade my account instead of having my site suspended. This practice of automatically suspending sites may very well be the normal procedure for most hosts thus the reason for my post today. Please share your opinions on this topic.

How do you limit CPU/RAM per account on a shared web server without virtualization? Something like what Dreamhost is now offering, for instance for user "john", assign 256MB of RAM and 10% of CPU. Without Virtuozzo and friends.

I have a dedicated server with CentOS and cPanel/WHM
I want to know how would I limit each user usage of RAM and or CPU
I see HUGE web hosts are doing that , they give you 9999999 diskspace and 99999999 bandwidth but they limit your RAM & CPU use to a tiny number
I want to know how could I do that in order to keep my resources good .

im trying to run APF, but i am getting memory allocation faliures from iptables. I havent gone nuts on the rules just a simple firewall scheme for cPanel.
Is it possible to run APF with numiptent set to 250? Is this something the VPS provider will increase without problem?
How about if i can i trim the APF down such that all rules will fit in memory? I already disabled the list downloading (near the bottom of the file) and i get less memory errors but i still exceed my 250 limit.

Bandwidth Limit Exceeded
The server is temporarily unable to service your request due to the site owner reaching his/her bandwidth limit. Please try again later.
Apache/2.2.11 (Unix) mod_ssl/2.2.11 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 Server at confidentchemicals.com Port 80
Bandwidth limit gets reset every first of month but what to do when users reached to this limit between 1 to 10 days?
we don't want to upgrade users packages or bandwidth limit rather than allocated.
why can't we reduce bandwidth limit?
