I have a shared server (root access) using Cpanel / Centos with suphp enabled.
Twice this week the sever's load skyrocketed and was unable to login to trace teh cause, had to reboot instead.
After reboot, I went to whm > CPU/Memory/MySQL Usage and saw nothing in red aside netstat (21% cpu). I'm not sure if this is the cause, but how can I trace the absolute user or script causing this spike?
Just few mins ago, my site went down so I went to check up through putty, and when i put Top this is what i got:

But after few mins, the server load went down to 5 What could've caused the huge server overload problem?
Server spec:

I have a cpanel, centos server that had to be rebooted due to the high load spike. I was unable to ssh in nor enter whm prior to the reboot so my only option was of course to reboot the server.
Now, I'm trying to trace the cause of the spike. RTG graphs show no indication of a ddos attack.
Inside whm, CPU/Memory/MySQL Usage shows no reds nor yellow warnings either except red for gzip (backup process) at 19% CPU. I doubt this is the cause.
This is from /var/log/messages of the logs slightly before and after the reboot.
Code:
Apr 9 13:31:49 server pure-ftpd: (?@70.250.201.162) [INFO] Logout.
Apr 9 13:32:05 server pure-ftpd: (?@xxx.xxx.85.3) [INFO] New connection from xxx.xxx.85.3
Apr 9 13:32:28 server pure-ftpd: (?@xxx.xxx.85.3) [INFO] New connection from xxx.xxx.85.3 .......
i want to ask any any setting or script can help medo the purpose?
i hope i can set a cron to trace server load every five minutes,
and help me record the load number on a log file,
by the way,
i can trace the past load of my server when i need the data.
Is there a method for tracking events prior to severe server load? I get these load spikes and am trying to track down their cause ..

I just moved my site from other VPS hosting into Liquid Web for around 2weeks now. I choose the VPS1 package with WHT promotion..
First impression, I do really satisfied with the VPS performance (server load average bellow 1), also the support team. All of my eMail was replied pretty fast in under 15minutes.
But, I do have one problem. Please note that I'm not complaining here.. I just want to ask other user of LW or maybe other hosting.
Almost everyday (well, I think it is).. I got a load spike on my VPS. It's always around midnight (GMT -5). Based on LW staff have informed me, it's because of the main node full backup process, which is can't be altered. The load spike make my site sometimes temporary can't be accessed, because the server load might become above 5, and the highest one is around 28.
Do WHT user has any similar issue like me? Any solution or suggestion I can take to minimize the effect of the backup process?
This is a RHEL3 box. It has a couple hundred sites, most of which are pretty quiet most of the time, lately I can't get the load below 3 most of the time. I've tried all the usual TOP PS and the rest, but I'm not seeing my problem. I've attached a text file with extended outputs. but here's what I'm seeing now from TOP and VMSTAT. I'm not sure what else I could be looking at.
I've been watching, and it seems to be Apache most of the time at the top of TOP, and I'm logging slow-queries for myslq, but there aren't many there.

I need some help tracing a spammer on my shared hosting cpanel server.
First off this is my configuration:
- apache 2.2 / php 5x
- suphp enabled

How much shared server load allowed is reasonable? My host currently allows up to 10% before suspension.
View 13 Replies View RelatedJust wondering if mysql load balancing is possible in a shared environment.
Example:
I have 3 shared accounts. On one server, I have the write and the 2nd and 3rd server I have the read (select). Or vice versa .. Would it be possible to create a php script to perform this function?
my server was down today and i want to know the reason can you please help me by pointing out the log files i should check?
Am runing CentOS 4.x with many domains on the server,
I have a dual processor, dual core server with 12GB memory.. It uses less than 4% CPU utilization and less than 5% memory utilization, but for some reason It's really slow to load sites...
I know this isn't much information, but would any have any ideas as to what could cause the slow speed?
If is anyone is available to look at it, I'll pay you (obviously).
Like if you try to make your own server, it would cost a few thousand right? Or bought one from IBM or something. If you rent a server, it could cost you like double that I notice or even more in a period of a year.
I was looking at the prices of Xeon 5420 and they are like only 400 or something. Motherboard, ram, hdd's shouldn't amount to too much right?
And companies are charging like 50 bucks a month for a 2 gigs of ram.
Or am I actually looking at this wrong and actually am looking at desktop components? So is bandwidth the cost for these prices? In the long run aren't people being ripped off?
My server is constantly crashing (halting to dead) and needing reboot literally every few hours. I cannot trace the cause of this whatsoever. Please help out.
CPU/Memory/MySQL Usage shows no accounts in red or yellow zone ....
Hi over the last week ive been having numerous problems with hosting accounts on 2 different servers which has lead me to think that my 'security' is not 'secure' and a malicious user is at play. im in the uk on broadband on a private connection to the internet - no-one else should be sharing this connection. This is the traceroute from my connection at home to the server ive had the most problems with - is this normal?
Traceroute has started ...
Is it normal for PHP to spike in cpu usage often? Which setting in php.ini can affect the cpu usage?
View 6 Replies View RelatedThe company I work for is doing a promotional site that will probably involve a good chunk of progressive (as in, not quite the same as streaming) video -- basically my best guess is that everyone who views the site will likely download between 6 and 50 megabytes of video depending on how long they spend on the site, etc... I would imagine most people would be at the low end of that, maybe 12 megs, but it's hard to predict...
The tough spot is there will be TV and banner ads purchased for this promotion, and it's not entirely clear to us how good response will be. It could be 5,000 visitors in a day ... it could be 250,000 in a day... the response to various advertising campaigns our clients have done has just varied a lot...
So let's say we have 150,000 visitors downloading an average of 12.5 megs of video - that's about 2 terabytes of transfer in a month.
How much should we expect to pay for that kind of data transfer, and are there good providers that will scale with us? I don't think we mind sacrificing a few hundred bucks our first month only to find that traffic was low -- but if it's going to cost thousands to move 2-3 terabytes of data via a CDN, what are our other options? Does anyone scale well even if it's unpredictable? I realize we have to pay some sort of premium for that scalability or it's not really fair to the hosting provider.. but what price range should we be looking at?
Anyone know of some good server load testers ( commercial )?
Im not looking for application based load testing, I need real web server load testing... need to see how much traffic this one site can take before it cries.
Is there a reason to set a high TTL for DNS? Like the standard is a few days.I set mine to 10 minutes. So whenever I do a change its propagated within 10 minutes. Is there a reason this would be bad? I realize it means more queries to my server, but 10 minutes is still rather long, not like thats going to totally hammer my server,

I'm having my first DDOS attack. Do people DDos servers for no reason? Beacause they are attacking an IP on a server that have not had any sites or any use on it for 4 years.
View 4 Replies View RelatedI can not find anything weird on the server.
Everything seems normal.
Why the traffic go high suddenly, then it drop to normal after a while.
well i made a PhpBB2 forum and im hosting it on my PC using wamp and no-ip but when my friend trys to access it he gets this.
You don't have permission to access / on this server.
I have port forwarded port 80 and everything else i could think of.
I'm having the oddest issue. For some reason, some of the websites on my server load fine, and some take a really long time to load (2 minutes).
Now, the server load is fine, and the size of the sites aren't the issue either. I've restarted Apache and a couple more services, and still the same sites seem to load very slow.
What could be causing this since it's only effecting certain websites?
i have a Centos server that install Xen and hypervm in it.
i have some vps in this server.
i restart server and after that i get this eror for run vps :
Could Not Start Vps, Reason: Error: Device 0 (vif) could not be connected. Could not find bridge, and none was specified:
how can i solved this problem ?
my server is : Centos5.2
I don't know whether possible or not if we can trace the dns from certain reseller webhosting and found where she or he bought the package... maybe it is important because we must know the reputation of the seller.
