Increasing The Apache ServerLimit In Apache 2.2.8 Version.
May 28, 2008
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)
Apache keeps increasing processes and when it reaches 256 value, it crashes. These are the values from our conf file. This doenst happen everyday, it occurs once or twice a week and at random timing.
Timeout 120 KeepAlive Off MaxKeepAliveRequests 100 KeepAliveTimeout 15
I enabled server-status and found request for index.html, is holding the processes. Only thing i see in access logs is ""OPTIONS * HTTP/1.0" 200 - "-" "Apache (internal dummy connection)""
my dedicated server is running using cPanel 11 apache 1.3.39 , php 5.2.4
i read a thread here in WHT says the " apache 2.2 with php 5.2.5 handle the load and doing high performance"
if it is true , plz anyone get the tutorials to upgrade it using /scripts/easyapache with GD libraries . and after upgrade will i have to re secure php again or what?
What will be best combo of those 3 which is main core for running almost any web server.Presently i have latest mysql,apache and php installed,but some people says how that is not good beacuse newest version arenot tested yet well enough.
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:
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):
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)?
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.
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.
I'm building a new server for a predominantly php5/mysql5 website and was wondering which version of apache to put on. I know there are some issues with PHP and Apache in MPM, but what's the performance comparison between Apache 1.3 and Apache 2 Prefork?
I am trying to install dedicated web server on my Slackware 12.0.0 machine. I am a novice in Linux, but succeeded in MySQL & proFTPd installation. The problem now in httpd compiling.
I downloaded the latest Apache 2.2.9, but it needs Apache Portable Runtime 1.3.2 installed. I downloaded 1.3.2 version and run ./configure

After that I am trying make and have error at the end:

I have total 5GB space wherein I can host unlimited domains.
When I uploaded my files ( for 4 sites ) I saw that I have used total 16 MB. But today when I logged in there I noticed that the cPanel shows that I have used total 22.75 MB
But I didn't upload anything that may take upto 6MB space
I just uploaded few images that may take maximum 100KB.
My hosting provider said this
"The extra disk space could be email messages stored on the server, mysql database files, etc... All these things are accounted for within your disk space."
But I replied that I don't use any database and I don't have any single email in my account so how that space can by consumed? Waiting for their further reply.
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.
Right now APC shm_size is set to30 and since I am only using about 20% of the RAM in VPS, I thought it would be best to increase it a bit. Now how do I go about doing that?
I'm trying to start a website on a shoestring budget, but my programmer and host want to squeeze more out of us. We currently have a Custom VPS, w/cPanel and WHM. Everytime I try to upload a file(s) more than 10 mb, it will not go thru. My programmer told me to ask the server to increase capacity, they tell me it will cost me. My programmer says the same thing. Now if my programmer can do it, I assume it will be done through cPanel. Is there anyway I can do it myself, so for example, a file of lets say 25 mb will get uploaded? I have access to my cPanel.
