16-40+ Load, Yet 90% Of CPU Is Idle (and) 0.00 IO Waits. What Could It Be
Jan 3, 2007
I have a really challanging task of knowing why and host to fix the situation
where at most times the CPU is totally idle and same for IO activity, yet the
load at most times is 16-40+.
For instance at time of writing this: The load is 16 now and linux says:
avg-cpu: %user %nice %sys %iowait %idle
0.49 0.40 0.90 0.00 98.20
(That's a whopping 98.20 idle state!)
How could that possibly be? And could you wonderful folks attempt to offer
me advice on how to find out why load is so high yet almost totally idle activity.
If you need various commands for me to run, let me know.
If there's also any ADMINS (with good status) that are willing to look at this and
think they can figure out this case, let me know. I'll gladly pay.

We've been frantically looking to move from this company called Media Temple for our staging server / email needs. Our application / corporate servers are hosted with The Planet.
Any one have any suggestions for a shared hosting provider between the regular $10-$20 / month range, having the following things:
Windows with .NET 2.0/3.5 and AJAX installed
At least 5GB storage
IMAP email with IDLE support or Exchange email (will pay more)
Ability to host at least 10 domains
Minimalist Control panel and Webmail preferred

I've got a server with FastCGI that at random produces 500 internal server errors. In the specific account the errors are as follows in the error_log:
[Wed May 21 12:01:29 2008] [error] [client 1.2.3.4] FastCGI: comm with (dynamic) server "/usr/local/apache2/htdocs/user/php-wrapper" aborted: (first read) idle timeout (30 sec)
[Wed May 21 12:01:29 2008] [error] [client 1.2.3.4] FastCGI: incomplete headers (0 bytes) received from server "/usr/local/apache2/htdocs/user/php-wrapper"
As you can see this unfortunately does not tell me anything.
Now viewing the apache error_log I see this
Code:
[Wed May 21 12:51:11 2008] [warn] FastCGI: scheduled the restart of the last (dynamic) server "/usr/local/apache2/htdocs/user/php-wrapper" process: reached dynamicMaxClassProcs (10)

All warnings so I'm assuming these don't mean anything.
Here's the php-wrapper:
Code:
#!/bin/sh
PHPRC=/usr/local/lib
export PHPRC
PHP_FCGI_CHILDREN=8
export PHP_FCGI_CHILDREN
PHP_FCGI_MAX_REQUESTS=500
export PHP_FCGI_MAX_REQUESTS
exec /usr/local/bin/php-cgi
Not a particularly well setup system for users and such but it worked for the user.
The software versions are as follows:
Apache 2.2.8 with Suexec on the FCGI
FastCGI (Latest stable and also tried a CVS version)
PHP 5.2.6
64 bit system
how to go about debugging this?

It seems that since my latest update of 12.0.18. Now everytime I login to the Admin interface of plesk. I am prompted to relogin several times when browsing using file manager or clicking on domains or sitting idle for like 15 seconds.
It can do this up to 5 times in a 5 minute period or while not even being idle.

I've been having trouble with my VPS for a while now. In the QoS alerts page in Virtuozzo it seems to be a problem with numtcpsock and tcprcvbuf, mainly numtcpsock.
Copy these into the browser:
i18.photobucket.com/albums/b106/gnatfish/qosnumtcpsock2.jpg
And when i run cat /proc/user_beancounters:
i18.photobucket.com/albums/b106/gnatfish/beancounters2.jpg
This line is particularly scary:
numtcpsock 164 164 166 166 7321
What do i need to do, to get the website running again? It's only one site on the vps a proxy. So i thought a vps would be able to handle one proxy.

Anyone know of some good server load testers ( commercial )?

I'm having the oddest issue. For some reason, some of the websites on my server load fine, and some take a really long time to load (2 minutes).
Now, the server load is fine, and the size of the sites aren't the issue either. I've restarted Apache and a couple more services, and still the same sites seem to load very slow.
What could be causing this since it's only effecting certain websites?

I would like to know how to check load via ssh and check files causing load?
I want the ssh codes for 2 different set of control panels, one with cpanel+whm and other with kloxo+hypervm
and I would also know how to check the files causing the load, such as some files could have been interrupted while processing, so they could be causing load some times, so I want to stop such processes if any are running on the vps on my friends accounts

I just got a futurehosting VPS recently and something is puzzling me. Is it normal that an idle CPanel virtuozzo VPS that has no sites on it should display "top" loads of between 1 and 4 regularly? I've been watching the load for a bit now and it keeps jumping between 0-4. When it goes 1 or above, the WHM panel becomes really slow, timing out... They seem to use a beast 8 core machine, so it would take some activity to cause even a 1 load..
I do not have much knowledge about VPS hosting, on a dedicated I would expect the loads to stay 0-0.2 at this point... Is the 1-4 load showing the result of heavy usage by other VPS users on the node? There is absolutely nothing that could cause a load in my vps as far as I see... Is this perfectly normal on any VPS?

You think this is funny? Not at all.
I'm on LON03 server and I recive yesterday from Future Hosting this advise about hight load.
I got then 1 month ago, and the solution was *JUST* to remove a phpBB website with 80+ users.
I do not believe that the VPS could get this kind of loads.
Funny is that the VPS was "monitored" by them at the same time. They say the load spikes out for times to times in a matter of seconds.
This load is taken from the Parallels Infrastructure Panel or even the Node Panel, not from the VSP itself. Even when I'm logged in.
I've been a client for 6 month, and 2 of the last 3 constantly getting CPU hight usage. Strange is, that I come from a 512mb/25gb PowerVPS server to a 1GB/30GB server, with the *SAME* sites.
Anyway, the prupose of this topic is to:
- check if anyone had this problem (problem is: beeing sure that this load is IMPOSSIBLE to be created from yout service)
- recommend a decent VPS provider besides Future Hosting and PowerVPS.

Due to high IO load server is going crash once a day.
I have optimized the MySQL, Upgraded the kernel but still it's same. The SWAP seems normal.
Now probably it is due to high traffic of http or emails. How should I diagnose and fix it? I am in big trouble.

the loads on my server is VERY HIGH and it needs to be upgraded fast.
I really have no clue as what to do... and i do not know any expert other than you people here - to help me out and put me on the right track.
i was thinking of
1) Getting a server with better CPU and more RAM
2) Load Balancing
However I know nothing of load balancing (other than how to spell it correctly )
1) Which of the above two options should i choose?
2) what are the extra costs in load balancing?
3) what should i know about load balancing before deciding?
4) How does load balancing work? I know there are two server - like one for database and one as webserver... but how does this work together?
5) what config should i be looking at in the two servers?
I'll stop here else i can go on and on and on...
I am giving the details of my server and service below, in case you guys need it.

We host a large number of small websites and are looking for high-availability and the ability to do maintenance on our application servers, so I'm looking for a load balancing solution. At this point, I'm considering Zeus ZXTM LB software, the Coyote Point e350si, and potentially an F5 1500 LTM.
The F5 solution is a total budget buster, and the Coyote Point UI is rough around the edges, but I've used them and they are reliable. Zeus looks like a winner with a great UI, but I haven't heard much about their reliability.
Bandwidth requirements are low at this point, so this is mostly about reliability and ease of configuration of a moderately complex set of services.
Any opinions on these vendors, or alternates I should consider?

I'm looking at load balancing a group of servers located at different data centers.
How feasible is this? Which options/solutions should I take a look at?
I would like to route using some sort of IP tunneling or similar so that the user doesn't see ww1.domain.com etc.
I will be distributing the load of the static/dynamic web pages, no database clustering.
I would prefer something a bit more intuitive than round robin. Perhaps directing incoming traffic based on existing server load etc.
Most of the load balancing solutions I've looked at assume all your servers are on the same local network.

I'm just curious, how many around here use load balancers in front of their webservers, and what kind of traffic do you push with them? (What kind of load balancer as well) Any other specifics would be nice as well.
Also, do you have failover for your load bal?

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)
