High Load Average
Dec 5, 2007
I have a new Quad core server which has a high load average. Only hosting about 200 sites on it and they are not database sites. Only a few MySQL sites.
Here is the output from top:

I have to move about 50 GB each night from one server to another.
This is the command I'm using:
Code:
/bin/nice -n +19 scp -c blowfish -l 18000 -P 22222 root@XX.XX.XX.XX:/backup/dailybacks/*.tar.gz ./
There is no private lan so i have to use internet. I'm using blowfish, which will reduce cpu load, and also limiting bandwidth transfer, usign -l 18000. How ever, I still do see some high load averages..
Do you have any other suggestion to optimize CPU performance while running scp?

What would you call a high load average? What is the top number?
Does this look unhealthy?....
1:48PM up 562 days, 18:14, 4 users, load averages: 11.15, 9.11, 6.48
2:14PM up 562 days, 18:39, 4 users, load averages: 0.85, 2.38, 3.94

PRODUCT, VERSION, OPERATING SYSTEM, ARCHITECTURE
Parallels Plesk Panel 11.5.30 MU #44 CentOS 6.5 (Final) 64bit
2 of our our servers are suddenly experiencing high Wait I/O Times, and high Load Averages during the backup process. During this period the Plesk grinds to a halt, sometimes crashing out completely (although SSh is still possible. We have been in talks with our server suppliers (assuming this would be node related) however they have done a lot of testing etc. and categorically state the node is fine , with no other users affecting it.
STEPS TO REPRODUCE : We backup the server using the scheduled backup service and Wait I/O immediately goes up.
ACTUAL RESULT: Plesk downtime / Website downtime
EXPECTED RESULT: No downtime, successful back up
Some other info :
All other processes (MYSQL, apache, Nginx etc) are all running between 1 - 10%
Partition "/usr" utilization 4.2% used (1.81 GB of 43.3 GB) (?)
Partition "/var" utilization 50.6% used (61.8 GB of 122 GB) (?)
We are struggling to identify what has changed on the server that would cause this sudden change.

If everyone can take a look at this (while all domains were turned off) and give me any advice to what is eating up resources so badly? The load averages are at 1.3+ with only yum trying to run on the box and it has already been running to nearly two hours were this would typically take 10-15 minutes max prior.

I have a VPS, and i wanted to know if the CPU / Load Average that shows at my Plesk control panel reports only the usage of my part of the server cpu, or if it is the real/complete cpu usage for the entire server?
So in a simple way, is another user with a vps at the same server is doing a high cpu task at is vps, will it show at my plesk cpu load average?

My site is running really slow at the moment. I checked Virtuozzo for resource usage, and it has been saying this for the past 1/2 hour.
CPU Usage: 0%
Load Average: Varies between 0.88 and 1.3 (anything over 1 is full capacity, and critical)
How can the load average be maxed out when my site hardly uses any CPU usage?

I have a server with Core2Duo E6600 CPU, 4 gigs of RAM and 2x250 GB HDD's. What is the "normal" load average I can expect having ~50 websites running on it with medium visits. My current load averages (and most of the time ones) are:
load average: 0.24, 0.13, 0.16
Is this "normal"?

I am trying just to extract the 5 minute load average from the output of a uptime command.
The output is as follows:
15:30:23 up 5:42, 3 users, load average: 0.03, 0.06, 0.08
So the value I need is 0.06.

I have a cPanel server with 4GB RAM
My server hangs time to time, once or twice a day. This is the last status when it happens.
Server Load 75.90 (2 cpus)
Memory Used 92 %
Swap Used 65.78 %
When I was still inside SSH when it happens, the processes I can see inside "top" are a lot of httpd processes.
So I "killall -9 httpd", I had to do it 30~40 times
#killall -9 httpd
#killall -9 httpd
#killall -9 httpd
x 30~40 times until no pid process found & the server load is back to normal.
Before that, I check httpd fullstatus, they look very normal, same goes to what I see inside WHM Apache status & cpu usage status.
At first I thought it was a memory problem after consulting with a server admin, so I replaced all 4GB new ram stick (such a waste)

I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
My current server stats:
Dual Xeon 5130
4GB RAM
250GB
50 Mbit/sec
CentOS 3.9
Website traffic stats:
15,000 visitors/day
150,000 pageviews/day

I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.

I am running in a High load problem lately. I have one of those cheap 1and1 servers which was running fine until 2 weeks ago. Once I rebooted accidentaly, it did not come back with some unrepairable kernel errors and I had to re-image it.
I chose to reimage the server with CentOS 5, for better support. The new re-image worked fine for some days, at least so I thought and now I am having high loads. The server crashes if not monitored every moment as the load is unpredictable.
Just a restart of the Apache will bring the server back to normality, but I am not sure if it is apache or some other script to be blamed.
I have beeing monitoring through apache server-status, but I cannot organize something unusual in the high load moments.
At this moment for example:
top - 09:00:36 up 15:43, 3 users, load average: 3.57, 4.60, 5.32
Tasks: 144 total, 2 running, 142 sleeping, 0 stopped, 0 zombie
Cpu(s): 10.6%us, 6.5%sy, 0.0%ni, 18.7%id, 63.5%wa, 0.2%hi, 0.5%si, 0.0%st

My VPS holds about 80 domains and low-use accounts.
Every night, from around 1.30am, the load suddenly skyrockets and will usually be around 5 to 10 for a few hours. Occasionally it'll spike to 30+ for a few minutes.
I had some antispam software running, and a couple of other packages (mail queues, mail manage etc), so I disabled all of that and removed all the crontab entries etc.
It's not really made any difference.
I can see the load stats going back 8 hours, as part of the ASSP spam package (I've just left the ASSP server load cron running just so I can continue monitoring it!)
Can the apparent load on my VPS be caused by other VPS's on the same node?? So in reality, my load is fine but is being affected by other people's VPS's?
I hope that makes sense. I'm 99% sure that my VPS is 'clean' (in so far as cron entries)
I'm asking the question because I took a second VPS on the same node and that one too has high loads overnight when there's nothing running on it (ie, no add-on software, no Cpanel accounts added)

Just signed up for a VPS with solarvps, which so far is lightning fast compared to my shared reseller account with RZ.
I want to create a script which checks the server load and drops me a text message on my mobile if the server load hits a certain level.
Just wondering what I should consider a high server load?
The server is the JupiterLX UK one from solar vps with over just over 800mb of SLM RAM.

Im in a VPS and everyday at the same hour goes very slowly due to high load problems.
The main site is a vBulletin forum and I get this error:
Too many connections
Ive change some details in my.cnf:
Quote:
max_connections=500
max_user_connections=70
But it didnt solve the problem.
This high load occurs at the same hour, I think that it is a cron job related problem, but this is my /etc/crontab
Quote:
# cat crontab
SHELL=/bin/bash
PATH=/sbin:/bin:/usr/sbin:/usr/bin
MAILTO=root
HOME=/
# run-parts
01 * * * * root run-parts /etc/cron.hourly
02 4 * * * root run-parts /etc/cron.daily
22 4 * * 0 root run-parts /etc/cron.weekly
42 4 1 * * root run-parts /etc/cron.monthly

i was previously using maxclients 256 in httpd.conf and the load was normal even when the server was processing 256 requests..
recently i had changed it to 320 coz of which my load had increased a lot.. Now when i have decreased it back to 256 the load is still high even when the no of requests are just 150..

How can you tell if your server was a victim of a DDOS attack? Server load goes so high that you cannot get in via SSH, and the server has to be power cycled to get back online. When it comes back online, load goes back up, we shut apache down, and the let the load come back down and then restart apache and everything is fine. Any way to determine what caused the load to skyrocket? System has APF, BFD, and mod_evasive installed.
