Can someone who really knows what they are talking about write me up a very quick parag. on the reasons why the internet is becoming overloaded w/ e-mail & why people don't get their e-mails besides spam filters filtering them, for example the grey/black list, detecting viruses in Word when the person's anti virus isn't picking it up, etc.

i have vps 512 MB ram From HostForWeb working Fine! in 160 websites! Hosted
But! in swvps.com with 2 gig ram! Low Working! OverLoad and CPU Usage is Red Alert
But HostForWeb VPS with 512 MB Ram good Working I Dont Know Why SWvps.com Is Low with 2 gig ram for me?
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 Relatedcurrently i purchase a reseller. when i click in server status, i found out that the detail is as below:
cpsrvd up [green]

Swap Used 9.51 % [green]
Disk /dev/sda1 (/boot) 13 % [green]

Disk /dev/sda3 (/) 88 % [yellow]
i found that the server load is in red color, and the last item Disk/dev/sda3 is in yellow color. may i know what is the problem?
My 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.

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.

View 3 Replies View Relatedhow can i find out what has caused my server to hang/overload once its rebooted?
I know that the SWAP maxed out but i am unsure why.
i am continously getting warning mail form cpanel cpu watch that my cpu got overloaded as like follows,
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
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 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.......
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.

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.

how check which database / user MySQL overload the server?
View 2 Replies View RelatedI 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

recently my mails are not been sent to hotmail and live users from the forum
I just checked by sending a test mail to my hotmail account but the mail wasn't recd. so
I checked the mail queue manager in WHM and the hotmail related mails were not traced.
how I can overcome this problem, I can send mail to hotmail if they are bouncing but when I don't find in the queue , what can I mail about them , when they ask an error id
I sent mass mail from vBulletin forum and I want to see status of those mails via ssh. I mean, I need to see how many mails is sent well, how many of them are still sending e.t.c
View 4 Replies View RelatedI recently placed an order (based on an add I found while browsing this forum) for a quad xeon. Everything went smoothly and their live support was very helpful. About 2 hours after receiving my confirmation I received an email containing a credit card form. The form is asking me to fill out everything I filled out during the billing process (including my credit card number, security code, and bank number). I know this form is basically a contract so they can bill me if I go over my bandwidth limit, but it seems pretty odd. Is this a normal thing or should I be weary about filling this out?
View 5 Replies View RelatedMy site/e-mail/etc that is hosted by Solid Internet has been down for almost 2 weeks. This is causing me some major problems.
Their support forum doesn't work, their phones go straight to voicemail, their voicemail inbox is full, they don't respond to e-mails or support tickets. I'm not sure what else I can do to find out what the problem is?
I've only just renewed for a further year too so I'm not overly keen on flushing all that money down the toilet.
I don't think I have any site back ups, certainly no recent ones so I don't want to lose everything which I assume I'll need to do to move to a new host?
