Server Load More Than 200 :((

[Baris]

Hi,

I have a dedicated server with WHM 10.8.0 cPanel 10.8.2-R119 CentOS 4.3 i686 - WHM X 3.1.0

It has a P4 3.0 GHZ Dual Core CPU and 1 GB DDR RAM.

Everything is good with the server.When the server load is low,it works really fast.But sometimes (nearly 10-15 times a day) server load goes too high.

I saw nearly 240 yesterday.But generally it goes up to 60.And it makes the sites down.

When this happen i stop apache via SSH then wait some minutes.This makes the server load down.

What do you advise me to do?I am about to loose my customers and this makes me really sad..

I fallowed the links and found that it is a problem with CentOS 4.3 Kernel.I have to downgrade Kernel.But i even dont know what kernel is.Where can i find howto documents about this?

Btw,thanks a lot jester.ro

login to a shell on your server, and type

uname -a

the output should be something like

Linux your.host.name 2.6.9-37.ELsmp #1 SMP Fri May 19 18:07:42 EDT 2006 i686 i686 i386 GNU/Linux

the "2.6.9-37.ELsmp" is the current kernel on your server.
That's what i have now.

You probably have 22 or 34, instead of my 37.


If so, while logged into your server,

wget http://people.redhat.com/~jbaron/rhel4/RPMS.kernel/kernel-smp-2.6.9-39.1.EL.i686.rpm

after the download,

rpm -ivh kernel-smp-2.6.9-39.1.EL.i686.rpm

Check to see if the new kernel is installed by default in grub.conf

cat /boot/grub/grub.conf

Default should be 0
And the kernel you've just installed should be the first one

title CentOS (2.6.9-39.ELsmp)
root (hd0,0)
kernel /vmlinuz-2.6.9-39.ELsmp ro root=/dev/sda6
initrd /initrd-2.6.9-39.ELsmp.img

After that, wait until your server is not that busy(night time) and reboot the server.

After it comes back online, check what kernel is using (uname -a)

Should read the new kernel.

 

[jester.ro]

The usual disclaimer should be applied to what i wrote above. It worked for me, and should be ok for you too, but if it isn't, make sure you can have the datacenter folks reboot the server and boot with the previous kernel.

Thanks a lot jester.ro

I am trying now.I will share the result..

 

[Baris]

It is ok..

My kernel version is 2.6.9-39.1.ELsmp now.

I will watch the load and share the result.The load is low now.I hope it goes like this..Thanks a lot again jester.ro

 

[jester.ro]

Glad i could help.

Also I thank Echelon17, he found this issue first

I have the same problem, my results when I do the above is;

2.4.21-40.EL #1 Wed Mar 15 14:30:04 EST 2006 i686 i686 i386 GNU/Linux

Means nothing to me

My server load is always 2+ first thing in the morning, sometimes reaching 4+

 

[WEB-PROS]

This kind of load could just be becuase of an overloaded server.

What are your servers specs and also check to see what program is using alot of CPU

 

[satishlive]

I have the same problem too

I have the same problem because some tims the mysql is get closed and sometimes the ftp gets closed.

uname -a shows the following think.

Linux servers.gc-servers.info 2.6.8-022stab067.1-smp #1 SMP Mon Jan 23 20:46:56 MSK 2006 i686 i686 i386 GNU/Linux

Is there something i can do ?

My server details are;
Processor #1 Vendor: GenuineIntel
Processor #1 Name: Intel(R) Celeron(R) CPU 2.20GHz
Processor #1 speed: 2199.795 MHz
Processor #1 cache size: 128 KB
1GB Memory


Server process always shows;
/usr/bin/perl /scripts/realperlinstaller Time::HiRes Net::AIM Net::SSLeay Archive::Tar GD::Graph Tree::MultiNode Tie::IxHash HTML::Entities IO::Tty Bundle::DBD::mysql CGI MD5 Digest::MD5 Expect Mail::SpamAssassin Net::DNS Bundle::Interchange Geo::IPfree Digest::SHA1 Sys::Hostname::Long
at around 79%

That's probably the old old problem with CPAN.pm. Kill off the realperlinstaller processes, upgrade to the latest cPanel release for the tree you use, make sure perl is v5.8.7 and if not upgrade using the package on layer1.cpanel.net

Thanks guys.

Found this http://forums.cpanel.net/showthread.php?t=50628&highlight=cpanel+continent+loop , so hopefully it'll do the trick.

 

[tazman2000]

Well updated to WHM 10.8/Cpanel 10.8.2 ......and now the server load is worse than ever......9.87 when I got up this morning, it used to only ever reach 4 on the older version

The load seems to be coming from GZIP now!! Any ideas?

 

[chirpy]

gzip is probably your backups running. Login and have a look at the output of ps:

ps axf
