Apache Httpd Service Crashing

May 17, 2008

It's been happening on both my old and new server, was really hoping this would be fixed.

Basically, the httpd/apache service crashes or goes down making domain names and sites unable to load; although cPanel/WHM still accessible. This would go on for about 5 minutes OR until I restart httpd in root.

sites simply do not load or just timeout after a period of time.

This has become extremely annoying for both me and my clients because it makes it seem like we have downtime.

Apache :: HTTPD Crashing On Its Own

Jul 12, 2013

httpd 2.4.4 x64 with php 5.5 x64 and mysql 5.6 x64, it worked just fine the first few days, but after a week or so, I'm starting to get this error:

[mpm_winnt:notice] [pid 1928:tid 552] AH00428: Parent: child process 8092 exited with status 255 -- Restarting.

What can cause that and how can I fix it?

Plesk 11.x / Linux :: How To Stop High Number Of Httpd Processes Crashing Server

May 17, 2014

Our server is running; Plesk 11.0.9 and CentOS 5.7 it has a Q8200 CPU @ 2.33GHz and 2GB of RAM. Now there are just two websites on the server plus a couple of redirects/forwarding domains, although lots of domains are still on the server but turned off in Plesk. Both websites are OSCommerce sites and I just need to keep these sites going until the end of the year when we will switch to our new Joomla based website.

We have seen an increasing number of server crashes and after various checks of the logs, fitting a new BIOS battery, check of the hardware by EasySpace who host the server, installation of ClamAV, LMD and RKHunter (which did find some Trojans and Suspect software), I have traced it down to some external Http activity that is taking all of my CPU time and RAM. Here is a screen capture of the Htop listing and when I killed these processes the CPU and RAM went back to normal. The problem is that I usually have to restart the HTTPD service and sometimes things get so bad that the server crashes and I have to request a power cycle.

Apache Keeps Crashing

Feb 25, 2008

I've been having problems for the past two weeks. Apache and MySQL kept crashing. I tweaked MySQL, and MySQL stopped crashing. But Apache still crashes, sometimes twice a day, sometimes once every few days. It's driving me crazy. It started around the same time I acquired a new customer, so it's possible the customer has some sort of script or something that is causing problems, but I'm not quite sure how to determine whether the problem is the server itself, or if it's the customer.

So here am I, asking you experts for whatever assistance you feel willing to render. Even if you only merely read it, I thank you for at the very least taking the time to read it. Thanks in advance for any and all assistance given. That being said, here's the information the "How To: Request help from the experts" sticky recommended giving. I also took the liberty of including httpd.conf and my.cnf. I apologize if that resulted in being too much information, and humbly ask a moderator to "white out", or so to speak, (or at least point out) the information that shouldn't be shown.

Linux OS: CentOS release 4.6 (Final)
Kernel Version: 2.6.9-023stab044.4-enterprise

Apache :: ISAPI DLL Crashing

Jan 29, 2013

i have custom dll built with Delphi that used to work on IIS 5/6/7. After i migrated to apache, DLL started to crash after an hour or two and i have to restart the server. The error was something about bad header. Since the developer says DLL is handling reponses OK and i can't get anything with debug logging on apache side can i run DLL as CFG/FastCGI (not that versed with apache so maybe this question does not make sense)?

Apache Allocating Too Much Memory - And Crashing

May 17, 2008

I've got a complicated problem and I can't figure out what I need to edit to fix this.

I've been messing with the httpd.conf and php.ini files trying to optimize them as best I can. I've managed to get the load to stay pretty low all day, and everything seemed to be working fine. But then apache crashes.

(See screenshot for details)

httpd starts out with 70-150 VIRT memory, and it constantly goes up all day, and I've yet to see it go down. And, eventually it just crashes Apache! In the screenshot it's 502m, but I've seen that get as high as 800! And sometimes I even see a number like this "80376" no "m" or anything, just "80376"; I've no idea what that's about.

So what do I need to edit or tweak to fix this?

I'm on a cPanel linux server, Apache 2.2.8 and PHP 5.2.6.

Weekly Offsite CPanel Backup Process Crashing Apache/bind

Mar 19, 2007

Right 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.

Apache 2.2 And Httpd.conf

Mar 6, 2008

I recently updated to apache 2.2 and when I went to check

/usr/local/apache/conf/httpd.conf

I noticed that a lot of the stuff was missing from what I usually see in apache 1.3 Was a new file created when the update was finish? I used easyapache to make the update.

I was actually looking to change the

Keepalive
Timeout
MinSpareServers
MaxSpareServers
MaxRequestsPerChild
Etc...

But it doesn't look like it's in there.

Apache :: Httpd Can't Access SSL

Sep 28, 2014

I can't reach my website, I get a "corrupted content" error message in the browser.Looking into apache (version 2.4.7), I get

Code:
~$ apachectl -S
AH00526: Syntax error on line 22 of /etc/apache2/sites-enabled/000-default.conf:
SSLCertificateKeyFile: file '/etc/ssl/private/owncloud.key' does not exist or is empty
Action '-S' failed.

However, I double checked that the file is in the appropriate location and does contain the key, so maybe apache has no permission. afaik, it doesn't run as root all the time - or only for a short time?

permissions for the key file are as follows:

Code:
~$ sudo ls -l /etc/ssl/private/owncloud.key
-rw-r--r-- 1 root ben 1704 Sep 28 04:01 /etc/ssl/private/owncloud.key

, where ben is my normal user.

It was suggested to me on the httpd IRC channel that maybe apparmor was doing something wrong, but I don't know how to investigate that.

My Apache Any 1h Going To Down And I Force Run Restart Httpd

Oct 22, 2007

i ask of cpanel.net that why : my apache any 1h going to down and i force run restart httpd

cpanel :
Howdy,

This is occurring because your server is consistently hitting the maximum
allowed concurrent connection limit, defined by MaxClients in httpd.conf:

[root@part7 ~]# grep MaxClient /usr/local/apache/logs/error_log | tail -5
[Mon Oct 22 13:07:46 2007] [error] server reached MaxClients setting, consider
raising the MaxClients setting
[Mon Oct 22 13:32:03 2007] [error] server reached MaxClients setting, consider
raising the MaxClients setting
[Mon Oct 22 14:03:29 2007] [error] server reached MaxClients setting, consider
raising the MaxClients setting
[Mon Oct 22 14:16:07 2007] [error] server reached MaxClients setting, consider
raising the MaxClients setting
[Mon Oct 22 16:48:36 2007] [error] server reached MaxClients setting, consider
raising the MaxClients setting
[root@part7 ~]#

You will need to adjust this setting to a value which better accommodates your
server to prevent any further downtime.

Apache Does Not Restart After Editing Httpd.conf

Jun 12, 2009

I am having a problem on my VPS. I am running the latest version of Apache on Windows Server 2K3, and after editing httpd.conf to allow virtual hosts (#Include /conf/extra/httpd-vhosts.conf) and trying to restart the service, an error appears saying the operation failed.

I have even tried restarting/starting the service via services.msc

If I am not using the default httpd.conf Apache will not restart at all... it is very strange. I have also tried doing a repair of the installation of Apache.

Apache :: Rotatelogs Crashes When Used As Piped Logging With Httpd

Apr 16, 2015

I've got a problem at a local customer with rotatelogs.exe and the current release of Apache HTTPD 2.4.12.

I've downloaded the 64-bit zip-file (VC11) and installed the VC11 vcredist in both 32- and 64-bit version.

The project is to upgrade apache 2.2 to apache 2.4. I've adjusted the configuration and added rotatelogs for log rotation for error_log and access_log.

The configuration is 100% correct, I can copy the line to cmd.exe and it runs correctly.

Variables are set in global environment, APACHE_HOME is set with "/" instead of "" to get sure rotatelogs.exe is found.
