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).
I have a dedicated machine collocated at some hosting provider and after a while (14 days or so, but timeframe is not constant) it hangs for no apparent reason. It happened 2 times already. Nothing in the logs (it logs everything), nothing at all.
Before the commission the machine was running for a month without any problems.
The first time it happened the tech guy plugged in monitor and keyboard and could not see anything on the display. Before that machine was not loaded with any traffic, nobody should have actually known it is there (except for some DNS traffic). It took some 20 days of uptime.
The second time it happened was yesterday, after some 15 days of uptime.
I suspect hardware malfunction because I have 2 "identical" (OS & progs, not the hardware) systems running without any problems. It is an HP DL380 G5 machine, the problematic one.
PRODUCT, Plesk for Windows VERSION 11.5 latest update VERSION OF MICROUPDATE 11.5.30 Actualizar #39, OPERATING SYSTEM Windows 2008 Server Suddently with no apparent reason, MYSQL stops and Ihave to go to the panel and restart it.
Every Morning I have to restart MySQL thru the control panel in remote console of windows..Works all day long, and then stops at night..Should work as always did, for several months I did not even reboot the server, no I have to reboot the server to see if that fixes the problem. Latest windows update, latest Plesk for windows update, but I have the feeling that with the latest microupdate something has broken,
My site is being attacked by what appears to be a dictionary attack on my mail account. They are sending e-mails to random accounts at my domain from random e-mail accounts from somewhere else. Each of their messages is coming from a unique e-mail address and a unique IP address.
Now, we have some dictionary ACL installed that basically blocks any IP address that is caught doing this. So we are blocking tons of IP addresses, but they keep coming at us with new ones. We also have it setup so that the mail is rejected right away for any accounts that aren’t actual e-mail accounts of yours. However, they are hitting the server so hard that it doesn’t seem to be making any difference.
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,
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?
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?
I've got 25 domains on a Virtuozzo/Plesk8.6/CentOS5 VPS. Each domain has one up-to-date install of WordPress, most have very little traffic (average 200mb per month), maybe 2 domains get 5-7gb traffic per month.
I monitor port 80 connections and rarely see more than 10 at a time.
That should in my opinion be no problem at all for a VPS with 768mb guaranteed ram and 2.4ghz cpu. I've got 30gb hard drive spare too.
But.... about 8 or 10 times a day it grinds to a complete halt: server load at 500-1000%, sites timing out, plesk takes 3mins to load, often I can't even connect with SSH, and the plesk web server, apache
INSERT INTO module_watchdog_sys_stat (time, type, value, service_id) VALUES(FROM_UNIXTIME(1226404705), 'MAINMEM_USAGE', 17472, 11);
80 seconds sounds like a huge amount of time for a MySQL insert to me! Does anyone know if this is likely to be the cause of my trouble? Some problem with Plesk and the database? Or could it be something else?
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,

My server is so slow I don’t know where the problem is
Server Load from 2 to 8 Monthly bandwidth 1300 GB Unique visitor 4000 - 5000 daily Page loads 13.000 – 20.000
This is current server features

I got a new hard drive. After just completing the wonderful instructions on how to rename video files on the server, the new hard drive has just "misplaced" over 1200 of my exclusive videos!
I didnt erase anything, but now the hard drive can only see upto a certain letter, all after that has gone.........is there any way this hard drive can restore these files? its getting ridiculous now
I dont know much about what could be cuasing this so i come to you for advice, i am currently at wired tree on their VPS384 package with 348MB of ram and my site is really slow to load [url]sometimes it is so embaressing to show people i just dont bother, i am sure this is deferring visitors from my content how can i speed this up?
I can add more ram but it will push the price and if the price goes too high i might aswell move to a Hybrid with wiredtree.
problem with my server running CentOS 5.3.
I noticed that there are huge pings to my server from time to time, example:
------------------
64 bytes from HOSTNAME (server-IP): icmp_seq=0 ttl=60 time=2.93 ms
64 bytes from HOSTNAME (server-IP): icmp_seq=1 ttl=60 time=2.70 ms

64 bytes from HOSTNAME (server-IP): icmp_seq=12 ttl=60 time=2.74 ms
64 bytes from HOSTNAME (server-IP): icmp_seq=11 ttl=60 time=1205 ms
------------------
First I thought that it is network related, but most strange for me was that I did not have any packets lose.
Then I tried to ping from my server to other hosts - situation was the same - some ping were good and some were huge (700ms, 800ms, even 2000ms)
I checked:
cat /proc/sys/net/ipv4/netfilter/ip_conntrack_max
and it was 65536
Then I checked:
cat /proc/sys/net/ipv4/netfilter/ip_conntrack_count
and it was ~1600 so normal.
dmesg was showing such errors:
conntrack_ftp: partial 227 3331059707+13
Then I checked ifconfig, here is the output:
------------------

------------------
Strange for me was:
RX packets [...] dropped:2421127049
TX packets [...] dropped:46
I did not have such dropped information on all my other servers. Dropped counter for RX was constatnly increasing.
So I decided to restart all services on the server. After restarting network and ipaliases - problem disappeared. RX dropped counter is still rising, but I do not have any slowdowns on the server and pings are normal.
My question is - does anyone could have any idea what can casue my problem and how can I prevent this in the future?
i have a strange problem at my server ,
i hosted 1 wesite ( forum script with no plugins )
when my traffic consuption reache to 25mbs the server running very slow for hours although the load avarage is very normal 1-2 Iowait 3% ram consumption 8-10Gb
my uplink port 1Gb and of course my DC said the connection is normal with no limitation
the server specs are good
Quad procs 7200 ,16Gb ram ,15K SCSI speed
connections reache to 2000-2500 per seconds
My dedicated server starts to be a bit too slow.
But on Munin it seems just fine.
what can i do to solve this problem ?
This is the link to munin :

and this is what i have :
Quote:
Tier 1 Bandwidth: 2000GB
Operating System **Select One**: Ubuntu Server Edition (6.0x)
Memory: 6144MB RAM
Uplink Port Speed - Disc: 100mbps
Processor: Dual Processor Dual Core Xeon 5160 3.0GHz Woodcrest 2 x 4MB cache
My server gets 300 - 600 concurrent connections to http port 80, has a CPU load of 1 - 2%, has practically all RAM of 1 GB used, is running apache 2 and centos 5.
It tends to get slow and when I ban IPs that use many connections to my server (raping it), it becomes fast again. But soon after that new ******* users come which I again ban and the process repeats itself
I'm starting to think that maybe I just don't have enough RAM to handle them because it seems at least some of those users are legit. I don't however have even that much content that needs to be cached so I'm not sure what good RAM would do but perhaps apache just needs more.
Server is responding slow!
My server is responding slow
How can I prove to my web hosting company that the server is extremely slow and overloaded?
If I call support, they are saying that it is fine for them. But I've checked with different internet connections and it's slow.
I want to be moved to another server or get a partial refund or something. At this point my website is unusable during peak business hours.... and I get barley any traffic.
My server (Xeon 3.0Ghz) went down for no reason yesterday and ever since it was rebooted (and I've rebooted a couple of times since then), pages load extremely slowly or just timeout. Server load is constantly hovering around 1 and top stats indicate that the server's resources are not under heavy load, which is contrary to the usual pattern during peak times.
I've checked netstat and I notice a lot of SYN_RECV. Could this be a DoS attack? If so, what steps do I take to stop it?
