I have heard a lot of cases when customers used forbidden PHP scripts on shared servers and as a result their accounts were suspended due to the server overload. I am just wondering what scripts it is desirable not to use within shared hosting packages?

i want to kill apache/http and restart it again automatically. i need this because sometime we are not in front of the server to fix an overload issue immediately, which can affect a server very badly. i believe many of us already face this kind of situation and hope there is some kind of script or way to do this.

Is there a way to protect apache server from overload? For example Nginx has a module called SysGuard when system load or memory use goes too high all subsequent requests will be redirected to the URL specified by the 'action' parameter.

I have been receiving these a couple time a day lately and not sure what to do or how to go about checking what might be overloading the server. IF this looks familiar to anyone, I'd appreciate some helpful tips. I'm still a novice, but can muddle my way around the server if given enough guidance. Here is the email I've been getting:
"IMPORTANT: Do not ignore this email.
This is cPanel stats runner on host.myserverhost.com!
While processing the log files for user xxxxxxx, the cpu has been maxed out for more than a 6 hour period. The current load/uptime line on the server at the time of this email is
19:20:10 up 2 days, 7:06, 0 users, load average: 15.17, 13.24, 8.00
You should check the server to see why the load is so high and take steps to lower the load. If you want stats to continue to run even with a high load; Edit /var/cpanel/cpanel.config and change extracpus to a number larger then 0 (run /usr/local/cpanel/startup afterwards to pickup the changes)."
I guess my question is, how would I go about determining what is causing the excess load? Seems to happen even when not many folks are on my site.
I'm on a low-end dedicated server that I run 2 decent sized blogs on. I'm getting several traffic spikes a day where the load goes through the roof and I think I need my server optimized.
My server admin says I need a bigger server and he has never steered me wrong but this is ridiculous:
My blogs use Wordpress as its blogging platform....I know they hog server resources and I've recently installed Super cache so that seems to help.
I average about 5,000 pageviews a day and I would think even a low-end box should handle this but maybe I am wrong.

I am not sure if my dedicated server is being attacked or if it is legitimate traffic. I need help figuring out the difference and if it is an attack, how to prevent it, and if it is legitimate traffic, how to configure the server to handle the load.
My server information is below:
HardwareIntel Xeon 3220-Quad Core [2.4GHz
8GB DDR2
SATAII 500GB
SoftwareCentOS 5.3-32
Apache2
MySQL 5
PHP 5
When I do ps aux|grep httpd|wc -l I get the count of current connected clients of 259 which is always maxing out my MaxClients of 256. I had increased it to 512, and it maxed out, I had increased it to 1024 and it maxed out, and lastly I had setup to 2048 and it works, but slows the entire server down.
I think my apache is killing my servers with crazy overload with logs... how do I turn this off?
View 2 Replies View RelatedMy server is out of memory....how do I find which script or domain is causing for memory abuse on server?
Its Plesk server 3.0Ghz + 1GB Ram
the server is overloaded some times during a day.
There is one process of httpd witch use 80-90% of memory. Load increases to 90 or 200 :/
I installed strace and when the process appeared I run on that process and there is:
mmap(NULL, 364544, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0) = 0x2b25e60000
There is a lot of that entries.
I am using a AP7901, and at 12AMP I am getting a red led status overload. At 11AMP the led is green status, which is perfect.
Is this a problem? Shouldn't I be able to use 16AMP? Is it safe/ok to use more AMP?
My webserver keeps on overloading, causing pages to lag and mysql connections to get clogged. Each time it overloads, it's because of there being too many MySQL connections, and I really just don't know why there are so many. I am not sure whether someone is sabotaging my server or whether there is a hole in my php scripts that causes an abundance of connections, or some very slow query.

IMPORTANT: Do not ignore this email.
This is cPanel cpuwatch on xxx.com!
While processing, the cpu has been
maxed out for more than a 6 hour period. The current load/uptime line on the server at the time of
this email is
19:05:10 up 143 days, 20:38, 0 users, load average: 1.11, 0.69, 0.63

/var/cpanel/cpanel.config and change extracpus to a number larger then 0 (run

I searched on load average and found that average load for 1 cpu is 2 and default value is 5 to 10.but here i am getting mail for 1.11 itself.I changed the value of threshold of load average in stat and logs of tweak setting to 4.but no improvement.now also i am getting more than 4 mails for average load i.e 1.23 also
My questions are:
1)what is the criteria cpanel is checking for sending cpu-watch warning mail?
2)i am getting nothing more than rsync and exim at the time of overload(while using TOP command).So why now only i am getting warning mail?
what is the cause of this problem?
I was getting idea from internet to create account without stat/ log analyse function .But not sure how will it work and afraid of doing this.......
My problem is server overload.I think it's a mysql optimization problem. But i dont change any setting.

I have 3 questions.
1.) I have a user that's kinda knows a lot about linux. More than me. He has a lot of stuff on the system which I have no idea what it is. Is there any way I can install a SSH log, so I can monitor what he does in shell?
2.) My server seems REALLY sluggish. I ran a top in shell, and mysqld was taking up from 70% to 110% of the cpu. Is there any way to fix this or find out why? I've restarted the server, and it's fluctuating between 50% and 90% now.
3.) I think this MIGHT be related to the sqld issue, but I've received about 12 emails saying

I've got a VPS which is serving as the main server for a number of sites. Web Server, SSH Server, and Mail Server.
What I've got running:
Apache2, PHP5, MySQL5, Dovecot, Postfix
One of the sites is a growing forum with a MASSIVE photo album. This is the site where I notice the most slowness.
Changing the server software is not an option - Only optimization.
