Plesk 11.x / Linux :: High CPU Wait I/O And Load Average During Backup
May 20, 2014PRODUCT, 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.
High Server Load / High Swap / Lots Of Httpd
Feb 20, 2008I 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)
My Server Is Very Slow, High CPU, High Apache Load
Oct 31, 2009My server is very slow, High CPU, High Apache load....
I got a new server and i had setup a script on it.
No server tweaks has been done.
I run a filehosting site so it gets very slow when traffic is high.
Here is some info:

Server High Load/high Mysql Usage
Jul 2, 2009I 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
Serving videos
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.
Daily, Time To Time Cpu Load
Aug 9, 2007I have a dedicated server specs: AMD 3500+ 64 Bit CPU, 1 GB Ram, 160 GB Sata Drive. For 1 month, CPU load average reaches 40-50 value. This happens about 5-6 times in a day. When I stop httpd service for 30 seconds everything goes normal. I think this is not a DoS attack because it comes systematic, I dont believe no one makes this regularly except bots.
Maybe its a system service or a cronjob but it stops when I turn off httpd service?
How can I be sure about what's making this regularly load?
I also did set up a script which mail me when load average of system goes crazy and restart httpd service. But instant restart is not working to stop load increase.
High Load From High Iowait
Jul 2, 2008I 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

High Loads At Exactly The Same Time Everyday
Apr 30, 2009has anyone else noticed an unusually high load occurring from 9 till 11 EEST time on their servers?
I've been getting high loads everyday this week at exactly these times.
I'm thinking that this is a crawler/bot that is causing the loads, i've already installed dos deflate and there hasn't been more than 100 connections from the same ip, so I'm ruling out any DOS attack ... besides, what kind of attack only takes place for 2 hours a day at exactly the same time?
I'm on a cpanel system and would like to know which logs to take a look at to determine the cause.
Process With High Limit Time
Jan 16, 2008top output from my server shows a this user was creating a lot of proccesses, even this process has been running for about 30 mins, how can I limit the time a process can stay alive? I suspect it was causing a high load on the server when started.

High VPS Load
Jun 24, 2009My 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)
What Causes High Load
Apr 19, 2009I have a VPS with LXadmin control panel and 1024 Ram.

What Should I Consider A High Load On VPS
Jun 30, 2007Just 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.
High Load
May 11, 2007Im 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

Load High
Nov 28, 2007i 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..

High Load
Dec 30, 2007How 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.

Page Load Time And Host Speed
Oct 9, 2008What difference in page load time does it make if I move away from GoDaddy hosting? Or doesn't it make much difference? If it does make a difference, what kind of percentage improvement are we talking about?
View 12 Replies View RelatedRsync - High Load
Jul 25, 2007I am using rsync to transfer files (tar.gz) between servers. However, it makes server load increasing 3-4. Normally, server load can be around 1, but when doing the transfer, it can go up to 5+
Is there anyway to reduce the load when doing rsync?
MYSQL High Load!
Aug 23, 2007I am just a beginner and it is about a month that the mysql loads on my server is so high , I have checked the mysql processlist via cpanel and there is no account that takes high mysql and make it high , and even I have checked for any possible rotten databases. but still the server load is so high and I can not control it , even when I restart it just after a minute it goes up again.
just the spamd command takes a high CPU usage sometimes. what it should be from? the spamd for a special account!
I need to optimize mysql , and need help. please do not tell me to hire an expert , just help me thanks
and another question is that how can I check which account is sending spam and stop it?
High Load Average While Using SCP
Oct 22, 2009I 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?

High Server Load ...?
May 7, 2009do you know what my server having very strange problem my server load suddenly increas after every 2 or 3 days some time after 1 days but when we talk about those days in which server load is fine then that time server load very low almost 0.4 to 0.1 .
But on that high load day server load reached upto 500.
when i try to find out what wrong then i only get that there is too much connection of http when i kill httpd through this killall -KILL httpd then server load suddenly decrease and then stable.
