Exactly what mean?
I've one main web server, the problem is that many people (now including myself) are often receiving "Connection timed out" messages in their web browser when trying to visit websites. This web server is a CentOS 5 machine and the HTTP server in use is Apache 2.2.
Of course, I've considered contacting server admin people who will look at this sort of thing on a one-off price or manage my servers at a periodic billing rate - but I'd much prefer to see what others have to say here first... hopefully learn some new stuff. It isn't a huge problem right now, but it can be annoying browsing the websites because a refresh would be required to connect again. I've learnt everything I know about Linux etc myself so far, through the likes of WebHostingTalk.. now is time for me to learn about TCP, HTTP, Apache and more if anybody has any ideas about this problem.
When running netstat, I'm seeing a rather large amount of TIME_WAIT's, I'm thinking this could have something todo with the connection time outs?
Here is my netstat output for TCP: [url]- notice all of the HTTP TIME_WAIT's for gangsternation.net? (also, a couple of other sites with less traffic)
apparently the sysctl commands / config does not work for VPS's. any way to reduce the time_wait period? got nearly 900 connections in that state!

here's a typical connection from china:
tcp 0 0 72.18.203.114:80 222.213.72.22:3059 TIME_WAIT
This is pretty annoying because my server load is at 50% all the time because of chinese TIME_WAIT connections messing up my server at port 80.
I read something about MSL (?) and tcp_time_wait_interval but I don't know if that will do what I want.
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)
This is my free -m
total used free shared buffers cached
Mem: 1998 1903 95 0 45 542
-/+ buffers/cache: 1315 683
Swap: 2662 36 2625
Not good ....
I got 5 wordpress and 5 statics website on this server and 100 visitors by 24H00 each day.
Question 1 : Why the memory is so low and the swap so high ?
Question 2 : Why i don't find high usage process in top command ?
Question 3 How can i resolve this problem ?
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.
I am running in a High load problem lately. I have one of those cheap 1and1 servers which was running fine until 2 weeks ago. Once I rebooted accidentaly, it did not come back with some unrepairable kernel errors and I had to re-image it.
I chose to reimage the server with CentOS 5, for better support. The new re-image worked fine for some days, at least so I thought and now I am having high loads. The server crashes if not monitored every moment as the load is unpredictable.
Just a restart of the Apache will bring the server back to normality, but I am not sure if it is apache or some other script to be blamed.
I have beeing monitoring through apache server-status, but I cannot organize something unusual in the high load moments.

lsphp is my webserver (litespeed). The sleeping processes are my SHOUTcast servers.
The thing I am concerned about is the "94.3%ni". This is slowing down my server completely and I am not too sure of what it is. Can anyone shed any light on this?
My VPS holds about 80 domains and low-use accounts.
Every night, from around 1.30am, the load suddenly skyrockets and will usually be around 5 to 10 for a few hours. Occasionally it'll spike to 30+ for a few minutes.
I had some antispam software running, and a couple of other packages (mail queues, mail manage etc), so I disabled all of that and removed all the crontab entries etc.
It's not really made any difference.
I can see the load stats going back 8 hours, as part of the ASSP spam package (I've just left the ASSP server load cron running just so I can continue monitoring it!)
Can the apparent load on my VPS be caused by other VPS's on the same node?? So in reality, my load is fine but is being affected by other people's VPS's?
I hope that makes sense. I'm 99% sure that my VPS is 'clean' (in so far as cron entries)
I'm asking the question because I took a second VPS on the same node and that one too has high loads overnight when there's nothing running on it (ie, no add-on software, no Cpanel accounts added)
I have a VPS with LXadmin control panel and 1024 Ram.
the memory always 333-450 but now it is more than 800 and the VPS stopped I restarted it many times but after restarting it the memory gone crazy again.
So, how to know what causes high load and eating my Memory?
Anyone know of any good/cheap high-bandwidth VPS providers? Don't need anything crazy as far as processing power or RAM (512MB with no burstable is fine). Sorta like Slicebox's budget servers, which I've had good experience with.
To e upfront, the box will be used for a little bit of testing, etc. but mostly to seed the latest Windows 7 builds :p. Don't think Microsoft minds all that much...Win7 requires a legitimate beta key to activate (which I have, and I'm not giving anyone mine) and it's a whole lot cheap for them to let people download over BitTorrent than Akamai, which they normally use.
So, any ideas? EU isn't out of the question...anywhere with a lot of/unmetered bandwidth for cheap, and a VPS that's reliable + has at least 512MB of memory for prices comparable (or slightly lower than) to Slicebox.
I've a remote download site that uses tons of BW (about 900GB daily), and it uses sql connection quite alot - I've set it to max connection for my current server.
For now, I've the intention of separating main site with download server. where The main site will contains the sql DB. But my concern is, I want to buy a cheap VPS for the main site, but no idea if I need high BW and ram.
I've got a dedicated with LW.
I've had it for a while and during that time I've never seen the swap memory go over 20%.
A month or so ago, I had the server upgraded to 8GB of ram to make room for more planned sites.
Since then, the swap memory has gone rampant. It regulary goes to 93% used with less than 20% of the regular ram and really no load on the server.
I've contacted support twice about it and was told don't worry it's normal.
From what I've read in the cpanel forum, no it's not normal and may in fact be caused by bad ram chips and if it hits 100% could freeze the server.
There are no processes or users causing it, so It's something else.
Has anybody had this type of problem that they resolved and could share what they did to resolve it?
What is the point of a high end quadcore cpu with 7200 rpm sata drives ?
i see tons of offers with really nice cpu's with either a single sata drive or 2 drives on crappy fake raid.
I have old dual single core xeon servers under 50% cpu usage that end up hitting the disk IO wall before they ever get to over 60% cpu usage.
Either me and my customers dont user software thats crap and eats up cpu for no reason or im missing something.
i have a vps and its quite a new one since i just ordered it and transfered everything from my previous..
But im getting really high cpu useage and im wanting to know whats best ways to optimize this...
I host a podcast that's rapidly gaining popularity. At the moment, we push about 100gb/day of transfer for the episodes, but could easily double that in the next few months. I need a host that does at least 2tb a month with the ability to later upgrade to more. My operating budget is about 110$/month, but could go a little higher if needed.
Most of our activity is composed of sending files, so usage is pretty low. I'd probably only need a few gb to store the actual content (30mb mp3 files). It's also important that Adult material is allowed (the content of the audio podcast is explicit).
I'm aware of FDC and AT&T, but would like any other recommendations you guys could give.
Anyway I can trace down who is doing it or what is going on?

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 know about high CPU usage and how it works against a webmaster when his host decides to suspend an account over this.
My question is what kinds of scripts usually cause CPU Usage to bulk up.
Basically what the script is doing, that just makes it happen.
I tried Google, but i guess poor choice of keywords .
I found many processes like this from a user log, this is a forum site, >>

Just signed up for a VPS with solarvps, which so far is lightning fast compared to my shared reseller account with RZ.
I want to create a script which checks the server load and drops me a text message on my mobile if the server load hits a certain level.
Just wondering what I should consider a high server load?
The server is the JupiterLX UK one from solar vps with over just over 800mb of SLM RAM.
