I'm having some problems with my exim. The mail queue backs up constantly and now my server load is increasing like crazy when exim is running.
I ran this command tail -f /var/log/exim_mainlog and the log has been listing for probably 15 minutes now and its still not done.
My VPS load high because of much mails in mail queue. And when I mails it gone to normal. Is there any script which delete mails in queue in every hour or any other solution for this?

But after few mins, the server load went down to 5 What could've caused the huge server overload problem?
Server spec:
64 3500+
1Gb of Ram
I have a cPanel server with 4GB RAM
My server hangs time to time, once or twice a day. This is the last status when it happens.
Server Load 75.90 (2 cpus)
Memory Used 92 %
Swap Used 65.78 %
When I was still inside SSH when it happens, the processes I can see inside "top" are a lot of httpd processes.
So I "killall -9 httpd", I had to do it 30~40 times
#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.
Before that, I check httpd fullstatus, they look very normal, same goes to what I see inside WHM Apache status & cpu usage status.
At first I thought it was a memory problem after consulting with a server admin, so I replaced all 4GB new ram stick (such a waste)
My server is very slow, High CPU, High Apache load....
I got a new server and i had setup a script on it.
No server tweaks has been done.
I run a filehosting site so it gets very slow when traffic is high.
Here is some info:

I dont know much about server managment...
how to fix this so server doesnt go slow?
I have a site that is eating up my server resources and need to know what the best solution for this is. I'm thinking of getting another server just for mysql but do not know what specs the server should be to handle the current traffic/database load and have the site run smoothly without slowing down to a snail's pace.
An alternative is to get another server just for the videos being served and leave the database and html on the current server. This is where I'm stuck and don't know what route to take with this.
My current server stats:
Dual Xeon 5130
4GB RAM
250GB
50 Mbit/sec
CentOS 3.9
Website traffic stats:
15,000 visitors/day
150,000 pageviews/day
Serving videos
I've attached screenshots of top and bandwidth usage per day. Hopefully with this information you could tell me if I need another server or if there are any things I can do to the current server to help things move faster.
do you know what my server having very strange problem my server load suddenly increas after every 2 or 3 days some time after 1 days but when we talk about those days in which server load is fine then that time server load very low almost 0.4 to 0.1 .
But on that high load day server load reached upto 500.
when i try to find out what wrong then i only get that there is too much connection of http when i kill httpd through this killall -KILL httpd then server load suddenly decrease and then stable.
I have a couple of sites that are generating errors because the server load is too high and when I check service status I am seeing the following: Server Load 21.49 (8 cpus)
How can I tell if the problem is one of my sites in my VPS or a different site on a different VPS on the same server?
server load is too high, can you suggest why too many process of qmail-smtpd even i stopped qmail and there is no more 25 emails in queue.

I know there are thousands of topics about this and yes i did use search function to try doing some changes myself and didnt wanna hijack someone else's topic so started my own
well my problem is i run a torrent site which puts a lot of load on my server. Just got upgraded to P4 2.8 ghz with 2GB ram , iam running fedora with WHM/Cpanel
i will do anything with server to put load down cos of load i have turned off my 4 other big sites ...
there are lot of sessions /task running of httpd by user nobody.
Due to this my server load going very high.
I am use opreting system fadora and cpanel latest version.
the site is running fine..
i have increased my maxclients from 256 to 320 ( reset all same ) my load has increased from avg 3 to 8.. is it a prob?
I've got a server that suddenly over the last three days has exploded as far as server load. Watching top I have some httpd processes that are using up all of the cpu and lasting for quite some time. How can I find out more about these hanging processes? I need to track this down as quickly as possible and find out what the cause is.
View 13 Replies View RelatedI have made any test with PHP x high volume sent with mail() and with direct STMP connection
I monitoring under WHM of my server the QUEUE (under mail queue manager)
With the first (mail()) I see only 20% in the queue, other is sent immediately
With the SMTP I see 100% on the queue and I must send manually (with delivery now) and sent is really slowly
We have an abnormal server load because of clamd.
View 4 Replies View Relatedif upgrading to that new server that I'll mention will probably solve my problems. Whatever help you can provide would be greatly appreciated. Below are the details:
In the GMT evenings and nights my current server gets so loaded that every page load takes 10 - 30 seconds. Even the pure html pages will be so slow to load. It seems that after a certain treshold it just suddenly becomes that much slower. Not much middleground there. I have high MaxClients and ServerLimit values now and the error log doesn't say that they are exceeded anymore but that didn't help enough.
I have a high traffic website that is using latest version of apache (2.2.x) with the prefork MPM and apache is optimized, PHP 5.2.5 and APC 3.0.15.
I get 160,000 - 210,000 pageloads per day. 32,000 - 45,000 visits per day.
Most of its pages are PHP but shouldn't be too CPU or databes intensive. Mysql isn't used and I mostly used sharedmem (php's shm functions) for databases. 2 semaphores are quite heavily used but that can't explain how a few more users would make the server serve pages so much slower.
Swap usage is practically 0 and CPU user % usage is like 1 - 2 % and CPU system % is also about the same even during peak times. However the Average Load or whatever that "top" reports is 6 - 9.
My current server scecs: 1 GB Ram, Pentium D 3 ghz, CentOS 5 32bit fully updated.
I load all pictures and even the stylesheet from a secondary server by using href="$secondaryserverIP..." in the html code, so the main server practically just serves the pages.
My new server will have apache with the worker MPM and latest versions of every software. Also its specs are: 2 GB of RAM, Intel Dual Core Xeon 2.40GHz, CentOS 5.1 32bit fully updated.
I have a sophisticated netstat based ddos script that is an improved version of DDoS Deflate and while some of these slowdowns seem to have been caused by attacks that it then was able to defend me from, most of them are not. I am even protected from users who constantly have 7+ connections to my site and if someone has a way too high number of connections, the script won't even check if it constantly has it and the script just bans that user outright. It probably is banning a bunch of innocent proxy users too but that is a small price to pay.
Alright we just bought a new customer aboard with a ChatBox on the site it seems as if this chatbox is causing higher load we went from 0.00 to 0.68-1.12 now this happened on our old server before too with another chatbox. They use vBulletin any ideas as to what would be causing this?

How do I lower the server load? it looks like for mysql activity.
MySQL the last few days seems to be constantly the most demanding process in top, which it never was before. As far as I can tell, nothing has substantially changed with regards to traffic to MySQL driven sites on the server. Is there anything that might be wrong with the databases, etc., that might throw MySQL into a tizzy?
View 8 Replies View RelatedToday my server started to go off-line and each time i restarted it went down within couple minutes. So i looked into it and found that i had over 7000 emails in Exim Mail Queue. All of them are spam. I deleted them through WHM and now everything seems good again but....
My question is how can i check what caused this problem? Has one of my domains been compromised with and sending out spam? What can i do?
i'm running a windows 2003 server to host a number of websites.
unfortunatly it looks like i didn't correctly protect the SMTP mail server
i checked the 'badmail' folder in the inetpub and found there were upwards of 250,000 bounced mails there... some spammers were obviously having a field day with my smtp server...
i've now changed the settings so that realys are only accepted from 127.0.0.1 and anonymous access is now disallowed.
my problem is that when i start up the SMTP server again spam is continuing to be sent out because the Queue folder is apparently full of junk waiting to go out...
i've tried entering this folder but the computer hangs, presumably because there are so many there...
i've tried deleting and renaming the folder but even with the smtp server turned off i get an 'Access Denied' error...
what can i do to flush or empty the queue folder ?
I have two quad core processors and load is like 15.
May it be caused by switch if it doesnt let traffic trough properly?
if dmesg grep eth shows 100 full duplex is it normal or should it be 1000 full duplex?
how can I make it 1000 full duplex on centos 5?

I am currently hosting my website on one server with the specs:
2.8ghz Dual Quad-Core processor + 8 gigs of ram + two 500 hard drives with a 50 mbps unmetered bandwidth package.
My current problem lies in high server loads and very slow server performance throughout the day.
I am considering migrating over to The Planet onto server with the specs:
3.0ghz Dual Quad-Core + 18 gigs of ram + two 50gb hard drives with 2TB of monthly bandwidth transfer.
In an attempt to have great bandwidth pricing and server performance, I plan on downgrading my current server with my current host to a lowe-end server and keeping it only to host my VIDEO and MUSIC files with the 50mbps unmetered package. The Planet will then host my database and all other web related files on their new server.
Is this a good idea as an attempt to save money in bandwidth costs and eliminating my server lag issues?
I was offered a setup of a separate web and database server at my current host but from what I have read, no one touches the performance and reliability The Planet has to offer.
I have server load like 40.
Nothing lags.
Server has RAM usage 20% and CPU usage goes up to 25%
Swap isnt used at all.
Should I be afraid of server crash incase server load goes up to 60 or 80 without ram and cpu usage rising that much?
So the site got featured on [url]and now the server is drowning...
The Coppermine Gallery usually hovers around 30~50 users daily and now, 1800, and im at a lost as how I should configure mysql to take on such a load. right now it takes about 10 secs or more to load a page and sometimes it would time out. Because it si coppermine, all pages are dynamic and can't be cached -_-"

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 server load was above 200+ today on this specific time.
How do I check from logs what is going on? Where do I begin?
16:28:11 up 32 days, 22 min, 2 users, load average: 241.03, 108.69, 54.24

I'm having problems with incoming spam on my dedicated server the load average of the server is around 80 or 100.2 I know it's incoming spam because when I check the exim process I see a lot of ips from russia, germany, taiwan then I block that ips with the /etc/apf/apf -d ip command and then the load of the server drops down to 7 or less, so the cuestion is how can I detect and block the spammers ips automatically on the server? I have spam assassin running and blocks the spam emails right, the real problem is the high load generated for spamd application and all the incoming connections of the spammers ips on the server.
Server specifications:
Cent OS 4
Control panel: directadmin
Dual-Core AMD Opteron(tm) Processor 2214 HE
1GB RAM
Exim 4.68
Apache 1.3.39
MySQL 5.0.37
vm-Pop3d 1.1.7f-DA-2
Which command do we type to see what is causing a high server load?
I've restarted the VPS numerous of times, and I wish to found out the problem
