The values in bold are the CPU percentage taken up by each apache process.
So i had to need to each apache process,who can i reduce it?what config i have to change to reduce it?
its 2am night here, and my sites are down....now there is no way i have too much traffic at midnight, also all my websites are new !
this is happening consistently since today morning and im getting no support apart from jargon filled replies from customer care
how do i tweak apache settings and what settings do i make to avoid this ?
im wondering what will happen after few months when my websites actually have good traffic coming in ?
We have checked your server. Please see the load average and process list given below:
The value 4.42 was the CPU load average at the time. A normal load should be below 1.00. I could see that Apache service is causing high load in your server.
So you can tweak Apache in order to reduce the CPU load. Please check and let us know if you need any further assistance.

Ive recently installed installed and configured stuff on my new box but after, I realised abnormal memory usage.
Mysql server is taking 256mb, there are somewhere between 6 and 10 apache process taking up at least 40mb each.
Furthermore, when I do: top, I see that the memory usage is increasing by about 120ko each 3 sec.
I am running centos 5.1 and have a load of 0. Basically, there is no one on the server appart from me.
On the server I have at home running debian, I run all thoose thing and it take up 200mb
max.
I have server in LT, the network is so good, but i got problem with the apache, it keep going down because the process too high ( i think)
when i list the process it show me :

I am in a bind with Apache's multi process limit. Let me explain what I am doing. There's this website which has career details of all the football players since the beginning of professional football. They have a simple web form which allows you to look at a player's profile by entering his name or his 7 digit numeric id number (on that website).
One of my client wants a list of all the players with a certain "flag" in their profile. So I created an automatic form submission and HTML parsing script to get details of all the players with that "flag" in their profile. Let me not go into too much details and tell you that after applying a few pattern rules to the id number, the number of possible id numbers comes to about 1 million (instead of 10^7; each field can have {0,1,2,3,4,5,6,7,8,9}=10 digits, so net combinations = 10*10*10*10*10*10*10).
Therefore, to completely automate this process I wrote a script which would generate an id number, submit the form with that id number, and parse the resulting HTML profile for the "flag". If the script finds a hit on the flag, it stores all the fields of that player in a database. This script is working absolutely fine but the speed I was getting was about one check per second which means that I would have to leave the script running for about 11 days (to process all of about 1 million checks).
So i came up with this idea to divide the check into ten parts and i created separate scripts for each part. Now basically the first script checks for the first 100 thousand combinations, the second checks for another 100 thousand combinations, and so on.
The problem is that I am able to get only two of these scripts running at the same time. So it would still take me at least 5 days to get all the results. The rest of the scripts just sit there in the server's backlog. This is definitely due to Apache's limitation to handle multiple processes. The server I am using to run this script as well the target webserver both run on Apache2. I am sure it's not a problem with the receiving server. It has to be my Apache web server which is running the scripts. I have tried using mpm_winnt (on a windows server) as well as the prefork and worker modules (on a linux server) without any luck. Has any of you ever faced the same situation?
For those concerned about the legitimacy of this work, rest assured, this is absolutely legit. There's nothing in the website's use policy which restricts somebody from doing this. Moreover, my client hired me to do this only because the website owners were not able to hand over the data he required. They gave the stupid reason that they are helpless in providing the data because they don't have a system in place which would allow them to do a search restriction!
I recently switched from XAMPP to a self-setup WAMP installation using Apache Lounge's 2.4.9 package in order to improve performance, to have more tweaking possibilities and to solve some problems that I was not able to solve in XAMPP (e.g. creating large PDF files using TCPDF) on my local Windows 7 development PC.PHP is running as FCGI module, which I thought was a good idea to achieve good performance, but I am afraid I have messed up the configuration a bit.
What happens is that sometimes, PHP script requests do not seem to terminate(?), but I do neither know why, nor do I know what is happening. It probably has something to do with scripts that process kind of a larger
I've got a quite difficult problem which I don't know hoe to solve. We use a self created ISAPI module which is a "business server" running behind an Apache.
From time to time a client app crashes the server (the circumstances are not quite clear) - and because there is only one server process, all other clients crash as well. Here is an exemplary log of a crash:
Faulting application name: httpd.exe, version: 2.2.22.0, time stamp: 0x4f242d7a

Exception code: 0xc00000fd means stack overflow as I learnt. Therefore we configured mpm_winnt_module to use a 8M ThreadStackSize but this didn't work.
A solution might be that Apache starts for every client its own server process with the module ABCServer.dll. Because it is quite small and there are not thousands of customers this sounds like the perfect solution. No other clients/customers would be affected by a crash.
Unfortunately mpm_winnt_module supports only 1 process AFAIK. Worker and Prefork MPM are not available in Apache's Windows version what I read.
How can we configure Apache to start a new module process per client?
It should be a straight forward change. [URL] .... does not redirect to [URL]...... It simply tries to load /denver-cars/ and denver-cars is in the URL. Am I missing something here? I have tried moving it up and down the list of rules and have tried numerous types of flags to no avail. Everything else in the htacess works fine with out the line:
RewriteRule ^/(.*)-cars/ /newcars-in-$1/ [NC,R=301,L]

I'm looking to pass the entries to a web form, via Apache, to an external process (listening on a port say 4321) running on the same host as Apache.Is there a way to "coerce" Apache into doing this?
View 1 Replies View RelatedRight now I am using the built-in cpanel backup feature to backup all the accounts on my server to an offsite FTP backup account I have on a weekly basis. The problem I am having is that everytime the backup runs, the load (thats what I'm guessing is the cause) is crashing apache/bind, causing sites to be unreachable until I can restart the services. What options do I have to resolve this issue? Currently I already have spri installed, and it does help out a bit, but its still not enough.

At the time, I had to upgrade my plan in order to stay online. I would like to move to a new host, but the prospective hosts are all suggesting a dedicated server because of my CPU usage. I don't want to pay that kind of money, so I would really like to curb the CPU problem. Does anyone know how to reduce the CPU of a Wordpress blog?

View 2 Replies View RelatedHow to reduce downtime - multiple name servers ?
Say I have two different hosting accounts at two different web hosts. One at host1.com and another at host2.com. In both the hosts I keep the same files. I use an external registrar and use the name servers for one of my domains as follows:
ns1.host1.com
ns1.host2.com
ns2.host1.com
ns2.host2.com
What would happen in that case, if say host1 is down sometime? Will the name servers point to host2.com?
If this could work, then the probability of downtime of a site would become almost 0 .
Google will like this ?
Another question is how to easily sincronize both cpanel accounts?
Few months ago I bought new small VPS box (OpenVZ, 128 MB RAM) in order to place there a new monitoring node of my site monitoring system. Such small amount of RAM is a challenge for operating system optimisation techniques (OpenVZ doesn’t have “swap” as Xen does).
First of all I discovered that apache2-mpm-worker (Apache implementation that uses threads) consumes more memory (100MB) than the classic version that use separate processes (20MB). I had to switch to apache2-mpm-prefork version then.
Next unpleasant suprise: small Python app eats 100MB of virtual memory! I checked that virtual (not resident) memory is taken into account by VPS. I applied some tools to locate memory bottleneck, but without success. Next I added logs with current memory usage to track call that causes big memory consumption. I tracked the following line:
server = WSGIServer(app)
is guilty for high memory increase. After few minutes of googling I located problem: default stack size for a thread. Details:This line creates few threads to handle concurrent calls
Stack size is counted towards virtual memory
Default stack size is very high on Linux (8MB)
Every thread uses separate stack
=> multi threaded application will use at least number_of_threads * 8MB virtual memory!
First solution: use limits.conf file. I altered /etc/security/limits.conf file and changed default stack size. But I couldn’t make this change to alter Python scripts called from Apache (any suggestions why?).
Second (working) solution: lower default stack size using ulimit. For processes launched from Apache I altered /etc/init.d/apache2 script and added:
ulimit -s 256
Now every thread (in apache / Python application) will use only 128 kB of virtual memory (I lowered VSZ from 70 MB to 17 MB this way). Now I have additional space to enlarge MySQL buffers to make DB operations faster.
There’s even better place to inject ulimit system-wide: you can insert this call in:
/etc/init.d/rc
script. Then ulimit will be applied to all daemons (as Apache) and all login sessions. I reduced virtual memory usage by 50% this way.
Note: you may increase stack size on stack overflow errors. In my opinion 256 kb is safe option for most systems, you may increase if in doubt. Still memory savings are big.

I have registered a domain using godaddy. I have hosted my site on a server of my shared hosting provider(lets call them X).Currently I have pointed mydomain.com to the server and it is up and running.Sometimes, I have experienced downtimes.
In order to solve this problem, I have hosted a clone of my site on another server from another hosting company(lets call them Y).
1. I want mydomain.com to point to Y when X is down
2. again point it to X when it is up.
My main aim is to have my site live with less downtime. The probability having both servers down is very less.
I dont know if it is technically feasible, just a thought out of dirty mind. I tried to google but was not able to find an answer specific to my problem.
Can anybody tell me how to achieve this through godaddy domain.
Added note, My site is not a commercial site and I cant afford large dedicated servers with clustering and failovers.
I would like to know if there's any way we could reduce "conversion times" for videos while converting them with "mencoder" and "x264 codec"?
Is it possible to cluster 2-3 or more servers (Quad core/8GB RAM) so that I can reduce the conversion timings effectively?
The original video sizes are around 500-700MB on an average and I'd like to convert them using mencoder in x264 codec @ 500Kbps bitrate and 2pass settings.
Ofcourse it'll take atleast 1-2hours to encode 1 such video at these settings on a 'single' such server, so is there a way to reduce the conversion times to around 10-15minutes/video by using "parallel encoding" with x264 codec?P.S: I know how to form a cluster, using beowulf/rocks, etc...what I need help with is 'using' the cluster with x264 codec
I did a quick search on this and could not see it as already being posted
It seems quite a clever but simple idea - remove a lot of the oxygen from the air to help reduce the risk of fire. What do those of you operating your own facilities make of this? Is anyone already doing this?
