I had a 'VPSII' at 1and1 (Windows). The VPS II is advertised as having 256MB, and in Task Manager it would show physical memory as 450MB. When I first questioned this difference I was told the 450 included an 'allowance' for the OS - seemed reasonable.
I just upgraded to a VPSIII - which is advertised as having 512MB. Call me crazy, but I was expecting Task Manager to now report 706MB (450+256), but it only shows 550MB.
I called 1and1 and they said 'that's correct' - we give the smaller VPSs a 'boost' but not the VPSIII - WTF?
I have a Windows 2003 server with 2GB ram running IIS and SQL 2005 express. I noticed that the server only uses around 1.2GB of its physical memory (been a few days) while page file usage seems high at 1.1GB.
SQL server has been allocated a maximum 1GB of memory while IIS has no limitations on memory usage.
Server doesn't really show any slowness at this point (not a lot of traffic). But to my understanding other than the proccesses that always use some virtual memory (around 400mb usually), page file should be only used when there is insufficient physical memory? So is there something wrong with my memory usage, 1.1GB on page file while there are still almost 50% available physical ram?
I have a VPS and it worked well, the problem is if I install huge database which is more than 2 gigs, the VPS will hang because it has no physical ram to handle it. My host told me the only way is to get a dedicated server for a db more than 2 gigs. Dedicated servers have physical ram to deal with such db's.
I live near NYC, and it would be very convenient if I could have physical access to my colo'd server. I don't suppose there is anything in the $50/month range? If not, then I guess any affordable colocation on the East Coast?
My server (cent OS4, plesk 8) was frozen for a day and the NOC had to reboot it, here is the mail I got from my host:
>Your server was frozen, with a kernel panic. Ensure that you check your logs closely to determine how this happened,
After looking at the message log here is the part of the log when the crash happened: Is this really a kernel panic, I am not sure...

It looks to me like if someone has physically connected a keyboard and logged in at the NOC.
I use Iptable to restrict ssh access to my IP each time I connect remotly, so I dont' think a remote connection has been possible.

Looking at the httpd error log I found this lines before the crash:
[Sat Dec 08 00:44:40 2007] [error] [client 213.215.41.138] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind [Sat Dec 08 00:44:40 2007] [error] [client 213.215.41.138] client sent HTTP/1.1 request without hostname (see RFC2616 section 14.23): /w00tw00t.at.ISC.SANS.DFind
apparently somone doing server scan. maybe the 2 events are correlated and the server freeze could have been a result of some buffer overflow attack, but i sould be finding some evidences of this on the apache logs?
What direction should I take to investigate a bit further on this server freeze?
We have a windows 2003 machine that is currently responding properly to all services that it's running (including IIS and FTP), however RDP connections just close right away and the server isn't responding when a local keyboard & monitor is plugged in.
The last thing that I want to do is pull the power out while it's on - any ideas?
I tried a remote shutdown, but the response is: C:Users>shutdown /r /m HOSTNAME HOSTNAME: The entered computer name is not valid or remote shutdown is not supported on the target computer. Check the name and then try again or contact your system administrator.(53)
Are there any calculators, white papers, or other guidelines that provide guidance for sizing a physical server to be used for openvz or Virtuozzo for Linux?
i.e. if you want to run “x” VPS nodes totaling “y” disk space needing “z” number of processes, etc. you will need “n” CPU’s of at least ____ Ghz with ____ RAM, and ____ hard drive space of which ________ should be reserved for the operating system and openvz system software
Also for openvz or Virtuozzo for Linux, which RAID provides the fastest performance without trading off too much for hard drive reliability?
I have a VPS. And have had an issue both when it was 1Gig and now I recently downgraded it to 768m, because I am moving some sites to a dedicated.
However, the part I am having trouble grasping is that when I look at graphs from Munin, it will typically always show 200-400MB free memory (and free -m and top agrees with munin), but Munin shows 'committed' memory that is above the total Ram on the VPS and once the 'committed' ram exceeds the VPS limit, processes start failing.
So, why is 'committed' memory exceeding the RAM on my VPS, when Munin, free -m and top all show there is free memory available?
Code: root@server [~]# free -m total used free shared buffers cached Mem: 768 449 318 0 0 0 -/+ buffers/cache: 449 318 Swap: 0 0 0 Here's a graph that munin produces that shows the 'committed' memory exceeding the total memory. [url]
I just got a new server Dual E5520 with 6GB RAM, SAS 15k rpm raid10. It's running well. However, the memory usage is just around 2.5GB, even when I have more traffic. Here is the kernel info

Any idea that we can put more content into memory?
I'have a problem with my aps setup on sanbox.When i create on customer ccp when i click finish i have this error. I must only test.

I have a 512mb DV server with Mediatemple, which I am running 24 (ish) domains off (most of them static websites) and a teamspeak server. I would say MAX theres 10 users online at a time)
Now, I know its running out of memory because i get frequent QoS Alerts in plesk (kmemsize is apparently the memory size):
Oct 01, 2009 11:52:57 AMBlack zonekmemsize
I have attached my results (when I did top).
My questions are:
1. Should I be expecting to be out of memory running what I am?
2. Is there a way to see the problem domains (memory wise)?
3. Are there any ways I can reduce the memory? (I have followed this already: [url]
4. Where is the memory usage coming from (I am finding it very hard to understand TOP)
I am hoping someone with experience of these things can comment on memory usage on my VPS partition. The master server on which my partition sits seems to be running at full memory usage and I'm getting lots of fork and mutex errors in apache causing apache to crash several times a day.
I'm running Invision Power Board on there with an average of 100 users in the last 15 mins during most of the day.
oomguarpages and privmpages are reported in 4KB blocks.
Hello everyone.i run LAMP on a dedicated server at theplanet.I have a small vbulletin forum.
I m planning to move to a new server.Just a quick question.for my new hardware,do i give more emphasis to ram or cpu...i will be getting 2 gb at the minimum.
SO,is LAMP dependant more on cpu resources or ram?
I previuosly have a forum hosted on a VPS with a 512 MB RAM (OpenVZ) and at that time it was only using 300MB of ram during peak time but the server was always down due to harware failures so I move to a new host this time Using Xen with a 768 RAM now it is using all the RAM available which is double the ram that it uses before. Is it really normal for a XEN vps to consume more memory than on a VPS using OpenVZ?
Drive Space Critical on server Drive Critical: /dev/simfs (/) is 91% full

what i dont understand is where did it go. I dont really have much traffic and nothing was uploaded or downloaded. I dont have any automatic backups enabled. How do I get it back to the normal 40%
I do notice i have alot of cpu usage Top Process%CPU 77.4gzip Top Process%CPU 76.2gzip Top Process%CPU 75.9gzip
Which is also confussing to me because I am the only user. I didnt do any backups didnt have any major traffic. And my disk space "memory used" didnt change.
How much memory would I need to run a couple of websites, with gallery,postgresql,wordpress,dotproject,spamassassin on top of usual apache, mysql, php etc?
Most of the cheap VPS starts from 196MB or 256MB. 512MB upgrades are expensive :p
I am trying to optimize my VPS setup and can't seem to get it to use all of the memory that I have. I have problems even getting it to use half of it. What kind of changes can I make so that it uses more memory while reducing load? My recent MySQL and Apache conf optimizations I have read about here and other sites have sent my loads above 1, but the memory usage is staying the same.
I've a question with XEN VPS. I rented vps with sweden provider and its 20 GB HD and 256MB memory. The setup isnt bad, done within 1 day. I check inside the vps and its XEN VPS.
I tried "top" command and wow, I am supprised !! here what I saw Mem: 262320k total, 208708k used, 53612k free, 54680k buffers isnt it funny ? 50MB++ left(not yet run anything, no panel running too). is it normal ?
I have other vps running inside virtuozzo, and got 192 MB inside. even its running so many process inside(about 15) that takes about 5-10MB each, its still have more left than XEN.
I have this 512MB memory VPS plan from fdcservers.net and it kept running out of memory.
The memory went up and down like roller coaster every seconds although I switched off httpd. Anyone can tell me what RAM do they assign to my VPS? Here's the beancounter results: [Please find the result in the attachment] Dont know why webhostingtalk mess up the spaces between each texts.
We are running into yellow status often at our new VPS. We have been with the web host for almost 1 year and recently got moved to a new VPS. WHM often show a yellow status for Memory Used (80% or so). As per the web host, WHM shows RAM for the entire server and not just our VPS. So how can we determine how much RAM we are using so? And to determine if we are using more RAM than we should or if others on the server are the culprit?
