As you can see.. there are LOT of connections, checked the network traffic with the NOC, and there is no attack to this server, also, load average is just fine ( fine to handle thos 24000 connections ) :
When I SSH'd into my box, I received this message:
example.pl is on this server. HTTPD connections have been limited to restrict this script from overloading server. All servers that have hosted this file need to have extremely limited http connections or have this file removed. It is poorly written and intense on CPU/memory.
How do I go and allow example.pl to be run on my server again? I use it solely for personal sites, so I wish to not have this file blocked and be allowed to run. I've searched for almost an hour now so I figured I would go ahead and post to see if any more experienced members could assist.
i am using seperate server for sql .But my httpd server failed many time when i checked maximum number of httpd connection then my sql server using too many connection what is the reason of this problem . Is my sql server using as a slave in a ddos attack or sql server need http connection?
Im Searching for a good server at a real cheap price. I also need a new network connection (wireless) <<< do anyone know were i connect my new connection too because im using aol and tired of missing business calls so thank you also this is my Home Computer not a a office Computer.
Since the update I have a problem with my Firewall. I need to set "Allow all incoming connections" under "Server => Firewall" in order to connect over FTP with TLS (explicit). This was working before the update without allowing all incoming connections. How to fix this in the Plesk panel?
My Customers and I have Problems connecting to IMAP-Server. By moving through IMAP Folders I get the Massage "Unable to connect to your IMAP server. You may have exceeded the maximum number of connections to this server"
I know this Article: [URL] ... and all the other related to this issue.
my server will revert to its old host name and stop working. Old host name was (in) and the new one is (zonto). Then, the server will eventually crash HTTPD. There is enough ram, there is small cpu usage. HTTPD is restarted and then it says it can't connect to local host blah blah. I checked EVERYWHERE, the new host name is set. Is there a host name issue some where else? I change it via the hostname command and changed all of the files.
I am not being able to restart the server, or MySQL or httpd via SSH.
PHP Code:

For my website I have a server which houses all of my gallery IMAGES of my user profiles. There are over 100,000 images on the server and it's only purpose is to provide those images with http.
However, the http server also has PHP installed, and it's only purpose is for uploading new images. Therefore users eventually get redirected to the images server where they can upload the image.
This all works, but in the future I want to remove the PHP side to the server. I also want to change the whole server program from Apache to Lighthttpd. This is because, lighthttp is a very low overhead web server program, but also provides very little features.
So I was wondering, if I was to do so, and since PHP is not installed, then I would have to make the upload pages on the main http server (which has PHP and Apache). Then I would have to make the main server send the uploaded image to the the lighthttp server via some sort of the scp system call, via PHP. I know that this IS possible, but when it comes down to security holes and so on, would this method really be worth it?
Generally I want to have the lighthttp setup only because it eliminates having to have any dynamic content. Obviously this can also be done with apache (removing dyanmic content), but lighthttp may be more efficient for static content.
I have a server that has server load showing at 25-40 (once it was even 53!), running like that for hours. The server has 4 cpus - and yet the sites on the server seem to run fine when I check them. What I'm wondering is, what exactly is load in this context; and how can load run so high like that without the server crashing?
According to top, the load is caused by httpd processes running under user 'nobody', that often take up double digit CPU percentage.
Does Apache always run under 'nobody'?
Is there any way to trace an httpd processes - which account it's for, or which physical script or URL is calling it?
And for top itself, the TIME field on one server of mine is in the format xx:xx (e.g. 3:25), on another it's TIME+ and in the format xx:xx.xx (e.g. 30:02.77). What exactly does this mean? I would asume it's minutes:seconds and minutes:seconds:hundredths, but while watching top it doesn't seem to correlate with that.
a topic long time ago that my server load is frequently high.
I'm talking about something like this Server Load 158.86 Memory Used 28.2 % Swap Used 99.57 %
[url]
The only way to solve this problem is to identify the load earlier and kill all httpd process. What I did was
#killall -9 httpd #killall -9 httpd #killall -9 httpd x 30~40 times until no pid process found & the server load is back to normal.
On previous thread, I tried to update mysql & php and it works,
Right now again I am experiencing high server load again...
I'm very sure it's caused by httpd but I am still unable to find out the real cause of the problem and which account user is the culprit for causing this high load.
Can someone assist me by telling me where/how to begin with?
My Dedicated server is being slow - hopefully someone can give a helping hand
Processor: AMD Single CPU Dual Core Athlon 4200 Memory: 2048MB RAM Primary Hard Drive: 160GB Operating System : CentOS 4.x X86_64 Bit Control Panel: CPanel uplink port: 100
We have a VPS Server from one of the most reputable VPS Provider. We have 384 Guaranteed RAM and 1GB Burst. We have Dual Core AMD Opteron(tm) Processor 265 - 1795.503 MHz with 1024 KB cached allocated to our VPS.
It is only hosting 2 average forums (10-15 concurrent users in total) and 30 small websites, low traffic websites.
The problem we are having is, almost 3 times a week, the cPanel, named and apache services keeps stopping. I am monitoring our server when this is happen and prior to the event its only using about 300MB RAM and low CPU..
What could be causing this problem? Do I need to upgrade our RAM?
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.
I tried to update a plugin at my blog its a wordpress blog, as soon as the update was started that site on the server stopped working, (later on i closed the upgradation window), after few minutes website start working automatically, Now in my opinion I think that update process is still running in background thats why connections are creating continuously to that website IP.
[root@server ~]# netstat -alpn | grep :80 | awk '{print $4}' | cut -d: -f1 |sort |uniq -c 1001 serverIPhere its even touching 1500, I tried to contact my server support but unfortunately they can investigate the issue, instead they told me to check with the following command.
which is not an answer to my question. Can anybody please tell me why those connections are making to that website's IP? I don't think its a Ddos attack, because it was just started when i updated the plugin.
