I am using prefork MPM in apache because we are running php which is not thread safe.
I have a ServerLimit of 500 and a MaxClients/MaxSpareServers set at 500. However, the server seems to be stuck at 352 processes.
Any ideas of why that may be?
I am wanting to set the following in the httpd.conf
MinSpareServers / MaxSpareServers / StartServers
However they are not in my httpd.conf , I am running Apache 2.2.11 on a cPanel/WHM VPS.
How and where do I set these settings?
I have been seeing this error in my apache error log for a while
Quote:
WARNING: MaxClients of 1024 exceeds ServerLimit value of 10 servers,
lowering MaxClients to 10. To increase, please see the ServerLimit
directive.
why apache give out this warning, when its configured as "ServerLimit 1024" in httpd.conf
Quote:
<IfModule prefork.c>
StartServers 10
MinSpareServers 5
MaxSpareServers 75
ServerLimit 1024
MaxClients 1024
MaxRequestsPerChild 1000
</IfModule>
The Linux Server got down when the MaxClients 256 is reached.
Error Log:
"server reached MaxClients setting, consider raising the MaxClients setting"
So that I have tried to increased the MaxClients Value to 500, after changed the value in httpd.conf and restart I get following error message.
" [notice] SIGHUP received. Attempting to restart
WARNING: MaxClients of 500 exceeds ServerLimit value of 256 servers,
lowering MaxClients to 256. To increase, please see the ServerLimit
directive."
So that I tried changed the Server limit in /usr/local/apache/include/httpd.h header file. but it seems like there is no entry.
Apache Version : 2.2.8
So I have added the ServerLimit 500 entry in httpd.conf file and restart the httpd service. But still shows the same warning mesg. Please help me regarding this.
We have the Dedicated server for Flash Game Server with following configuration.
RHEL4 OS
2GB RAM
Intel(R) Xeon(R) X3210 @ 2.13GHz
Cpanel Installed.
Apache 2.2.8
PHP 5.2.4
MySQL 4.1.2 (MySQL Server is working in differend server)
I am using apache 2.2 webserver and tomcat 6 as app server.
I have two unix boxes (let say A and B) where apache is installed for load balancing purpose.
The issue is now and then I see that on both the server reaches to 250 busy servers which makes my site very slow and after some time the site is unaccessible.
When I see this I restart apache on both unix boxes and also restart my app server.
But that does not work. As soon as I start apache the httpd process ramps up to 12 (ps -ef | grep httpd) within a minute and the busy servers still remains at 250.
The only I have to do is wait and watch till the busy servers goes down to 250 and then site is back to normal.
Some times it takes hours for busy servers to go down below 250.
I dont understand that why even restarting apache and tomcat doesn't work. why the busy servers are still at 250. even after I restart.
This is what I have in httpd.conf
<IfModule worker.c>
ServerLimit 80
StartServers 2
MaxClients 250
MinSpareThreads 25
MaxSpareThreads 75
ThreadsPerChild 25
MaxRequestsPerChild 0
</IfModule>
I tried to increase MaxClients to 300, which also didn't work and apache or httpd process shuts down by itself.
Is there any where that I can check my MinSpareServers, MaxSpareServers values are good enough? Or they're too small, or too big?
View 1 Replies View RelatedI have a pages with high load - load avg is about 10-20.
and in the error_log of the apache message:

We switched to Debian Etch on our server. But we are facing a real big problem. We can not increase the MaxClients directive on Apache. It gives this error:
WARNING: MaxClients of 500 exceeds ServerLimit value of 256 servers,
lowering MaxClients to 256. To increase, please see the ServerLimit
directive.
ServerLimit is already listed on our httpd.conf. But it does not make any difference.
<IfModule prefork.c>
StartServers 20
MinSpareServers 10
MaxSpareServers 15
StartServers 5
MaxClients 500
MaxRequestsPerChild 3000
ServerLimit 600
</IfModule>
How can we increase the ServerLimit?
im using apache2, and in apache config i set maxclients value is 60.
it mean, my vps will accept only 60 clients at the same time.And when vps have more than 60 clients, all clients over are locked out till my vps have less than 60 connections.
But when my vps had more than 60 clients, apache is crash, ram is not full, and i must restart apache.
i want to larger the "MaxClients",
i add the MaxClients 1000 in the httpd/conf/httpd.conf and restart the httpd
but it looks likely not work at all,
what should i do else?
my apache is version 2
Noticed that our http.conf file only contains MaxClients but not HardServerLimit. Is it because we are running an older version of Apache where the server limit has to be compiled with that set? We are running: 1.3.37
Our management server has set MaxClients to 2000 and it seems to work. Have been doing lots of reading and this number may cause issues when the server spikes in traffic. Most users recommend a number below 500.
I am using Plesk 12 / Ubuntu 14.04
In PLESK 11 I could set maxclients, ServerLimit ..... in /etc/apache2/apache2.conf
But I cannot find these settings in apache2.conf.
Where to configure these settings, in which file?
I`m on VPS 768Ram WHM/Cpanel
when i check error log on apache i see that error around 5 times daily.
[error] server reached MaxClients setting, consider raising the MaxClients setting
the apache restart automatically (~3 second). and that the problem when user make downloading all connections CUT.
my httpd.conf
maxclients 150
maxrequestperchild 0
i can increase maxclients no problem but i don`t know if i need to do something else or not.
Is there any way to LIMIT connection ( if server get more than 256 connection it says SERVER BUSY and doesn`t accept any connection )
Since I upgraded to apache2.2 I dont seem to be able to find the "MaxClients" setting in httpd.conf.
I spent some time on google and aparently this has been taken out because apache2 is multi-threaded. What I do know is no more than about 250 people can connect to my server.
well now my server load is back to normal i.e 1 - 2
but i want to increase the maxclients limit in my httpd.conf..
when i did 312 and restarted it, it says the max is 256.. so how do i increase the limit
One of my sites gets around 10k+ visitors a day which has caused my httpd to be really slow.
My MaxClients is set to 250.
What should I do to get it back to normal?
Server Version: Apache/2.2.22 (Unix)
On our production service, we've been getting numerous malformed POST requests to some of our CGI scripts that are showing up as 500 errors in our logs. They are malformed in the sense that the actual content length doesn't match the Content-Length specified in the request.
Here's the most trivial example I can come up with that reproduces the problem for us:
POST /some_valid_alias HTTP/1.1
Host: example.org
User-Agent: Arbitrary/1.0
Content-Type: multipart/form-data; boundary=---------------------------41184676334
Content-Length: 769
-----------------------------41184676334
In addition to the 500 error in the access log, we see the corresponding error in the error log:
(70014)End of file found: Error reading request entity data
Based on the nature of the POST request and the error response, it does appear that Apache is doing the right thing here.
The POST never actually makes it as far as the script being targeted (/some_valid_alias in the above example); in other words, Apache returns 500 to the client, writes the error to the error log and never executes the script.
Is there a way to capture/avoid internal Apache errors like 70014, and return some other HTTP status besides 500 (like 403)? It's particularly annoying in our case, because our server sends us an email for all 500 errors.
So far, our best "defense" against these 500 errors is to disallow POST for these aliases, which normally just ignore the POST data anyway (when the request is not malformed):
RewriteCond %{REQUEST_METHOD} ^POST$
RewriteRule ^/(some_valid_alias)(.*)$ $1$2 [R]
But this won't work for all our scripts, because in some cases we do want to permit POST.
I've had this problem a long time now with my hosting network and decided to ask here hoping I get some good solutions, or if someone is willing to looking at this (I'll pay if they want).
Here's what I mean:
[url]
Problem is as you can see apache processes constantly rise infinitely, at least until I restart apache (/etc/init.d/httpd restart). The point of restart is shown in red lines.
And after restart, it goes down again for X amount of hours then eventually rises again infinitely until it's restarted again.
But the fact that after restart it remains down, it means it had the potential to be down all along.
So my question is: what could be causing this and does anyone have solution to keep them low at all times (as per graphs)?
I have the following Apache redirect code in .htaccess:
RewriteRule ^sap-latest-news/([0-9]*)/([A-Za-z0-9_-.]*).htm$ /domain.com/app/modules/content/latestNews.php?id=$1 [L]
This redirect works fine on Apache 2.2.8, but doesn't work on Apache 1.3.41
The following is the entry from error_log:
RewriteRule: cannot compile regular expression '^sap-latest-news/([0-9]*)/([A-Za-z0-9_-.]*).htm$'
A simple Rewrite is working fine in Apache 1.3, but the above regualar expression doesn't seem to be working on Apache 1.3. Does anyone know whether Apache 1.3 doesn't support it?
I am having an issue where I have a server that Directadmin is installed on. I go to the a url that is on the server and all i see is the default page of apache saying congrats, it is installed. Although there is no file like that in the public_html any longer and I can see my files in the public_html folder of that specific site.

I have apache 1.3 and PHP 4.4 installed on my CentOS 4.4
Can I install apache 2.2 and PHP 5.x on the same server? I want to test my scripts for compatibility and also to check the performance.
I dont want to break my current setup because it's a production server.
if you were to be presented with a choice to run Apache 1 or Apache 2 given you'd have more or less the same support requests etc, and the same underlying user requirements to implement either one or the other, which one would you choose and why?
I noticed that Hsphere Parallels control panel 3.2 release as may well other control panels, offers such possibility. Personally I've been educated from senior members of previous organizations to appreciate Apache 1 as the defacto version of the web hosting industry (choice here being apache 1 and 2, not IIS or any other web servers)
Could you kindly simply attempt to enlighten me given, indeed support for both will/might remain the same in the future?
I am facing while upgrading the current Apache version 2.2.11 to Apache 2.4.4. IIS 7.5 on Windows Web Server 2008 R2 is not redirecting requests to the Apache 2.4.4 which is on Windows Server 2003 R2. I checked the access and error logs of Apache 2.4.4 and there is no entry. The existing 2.2.11 is working completely fine with IIS 7.5. IIS is working as a load balancer in my environment, takes the https requests and forwards that to Apache, then it goes to the App servers. Here, self signed certificate is used between the Load balancer and the Web server.
I have followed exact same configuration as it was used in Apache 2.2.11 but installed it with a different port (444), later changed it to 443 before running Apache 2.4.4 as a service, turning off the Apache 2.2.11 service. And also, my Apache 2.4.4 is working completely fine when I access it through the Web Server level URL (through the server machine name). But it throws me an error 502 when I hit the Load Balancer level URL. Here is the complete error:
"502 - Web server received an invalid response while acting as a gateway or proxy server. There is a problem with the page you are looking for, and it cannot be displayed. When the Web server (while acting as a gateway or proxy)contacted the upstream content server, it received an invalid response from the content server."
how I can solve the issue? I am stuck with this portion for about 2 weeks now, it's really urgent to get it solved!
My observation that came through lots of trial and error, I believe that this has something to do with Windows registry!! I came to this conclusion as I uninstalled the existing Apache 2.2.11 and installed it back again, it throws me the same error that I am getting for Apache 2.4.4. Then, I matched it with the other web server, found out some differences in the registry created for 2.2.11 and changed in this one accordingly- now 2.2.11 worked fine in this web server.

View 5 Replies View RelatedI currently have a dedicated server running centOS5 and webmin. With help of folks here
I was able to bind additional IP numbers using webmin.
I have a small problem now. The idea of binding the IPs was so that I could create "true port 80" shoutcast connections on the new IP numbers. However, when I try this I am taken to the control panel home page (home page to that server). The config on the shoutcast server is set properly (using proper IP #) as I have been able to listen to a stream using the new ip number's (higher ports), but not the main IP number.
My questions, I hope, are simple.
1. Am I able to use these additional IP numbers for Shoutcast Port 80 (true port 80 - only one per IP #)?
2. If yes, do I have to make Apache use ONLY my main IP number, thereby releasing the others for Port 80 use? If so, how do I do this.

Also, any other items I may love/miss from upgrading?
