Windows: 2GB Physical Memory - 1.2GB Used - 1.1GB Page File Usage : Normal
Mar 22, 2007
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 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 just uploaded a wordpress site and it already used up 300mb ram. The site receives very little traffic so I doubt the traffic is the cause of the ram usage. Is this normal? my control panel is webmin
Normally on our slowest day of the week, RAM usage is around 20%-25%. We see RAM usage increase as more users hit the site, thus, RAM usage historically, has been tied to public bandwidth. Recently, RAM usage has been hitting 32%-35% on our slowest day of the week (as indicated by bandwidth usage). I am guessing that something is keeping apache threads opened and/or a cron-driven process which invokes httpd isn't finishing for whatever reason. This is only my guess after some research and looking at whm reporting and top. With my limited server knowledge, these are only my guesses.
1. What could be causing this increase RAM usage?
2. How do we find out what is causing it?
3. We did recently installed the OpenX ad server but there are no ads being served, we just implemented the CRON job for testing purposes. Maybe this could be the cause but how do we tell?
Sitemeter is telling me the site gets an average of 38000 page views a day.
The web host is telling us we're using 51gb of bandwidth a day on average.
This is not a video site, or a download site. This is an article site, with jpg images. Our biggest page has about 2.4 meg of images on it. The average page is about 1.34 mb's, counting the navigation images which repeat on every page.

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?
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)
I have a problem with my server. I am trying to make a subdomain, and it isn't working. I create it like how in all tutorials says here( click here ) . I completed all fields, but when i try to open the subdomain in a browser page, it's telling me, page not found / page doesn't exist. I have a dedicated server on window server 2008 for my website with a dedicated IP.
It seems that a user may get more percentage of memory purchased for real use. I've got a xen VPS which has access to all 8 CPU cores. Guess this is a good thing to be able to burst CPU resources
But this requires lots of kthread running to be able to access all CPU resources, which in turn consumes quite some memory, a valuable, limited resource on a small VPS instance.
The output above is grathered when almost no other services are running except sshd.
While XEN VPS surely consumes more memory than OVZ VPS, I would suggest the Xen VPS can be built in such a way less memory is required to just do the housekeeping.
Of course, that would imply careful provisioning, maybe less "overselling" for the sake of lack of a term. The bottom line is how we can reduce the memory usage, while ensure individual VPS instance can still have fair share of CPU if needed.
Is there anyway in the VPS kernel config which can disable access to certain CPU core, thus reducing the number of kthreads and etc?
I do not know if i have problems with my vps but "top" output looks strange for me. It looks like apache processes have huge VIRT parameter and all processes have huge SWAP param.
My VPS 712 guaranteed and 1024 burstable. I'm running 10 virt hosts with very small traffic. Totally not more than 500 visits/day. Most of sites are static and only two are PHP.
how much adding php to apache will increase memory usage on a VPS? This would be php5.
I need it to use phpMyAdmin to manage my MySQL database (actual site is running off tomcat but jspmyadmin won't work for some reason).
Or can someone recommend a database design tool (I've used toad data modeler before) which I can use on my home pc to generate SQL statements for execution on the server (and please don't say notepad).
I am trying to run tomcat on my linux server and I am getting memory allocation error. When I see check memory usage it is full, but when I check the cpu usage it show as this:
Am using Hypervm,my all vms are not using more than 512 MB memory but when i click on server as localhost the there is show maximum memory usage I have total 8 GB it always show 5-6 GB usage and never drop down, How can I fix this matters?
I was just wondering about DA memory load. Like CPANEL load around 300mb and LXADMIN about 20mb. I was going to get VPS with 256 only to host 40-50 church sites with just static html, not dynamic or anything. Greatly appreciated with your input. I'm still learning all of this
I have a VPS with 384 MB RAM, with free about 100-120 MB. I've upgraded to 512 MB (to have some other features...). I notice that the memory usage is always about 250-300 MB. For example, now:
Code: [root@host ~]# free -m total used free shared buffers cached Mem: 512 311 200 0 0 0 -/+ buffers/cache: 311 200 Swap: 0 0 0 But PHP tells "out of memory" in some tasks
The current PHP config is memory limit 192 MB (it was 96 MB, then I tried to increase). [url]
Code: <b>Fatal error</b>: Out of memory (allocated 19660800) (tried to allocate 39 bytes) in <b>##hidden##/includes/joomla.php</b> on line <b>3041</b><br />
I'm currently playing with my dedicated server, it isn't much but for learning purposes it's more than enough.
I have CentOS 5.3 installed on the server.
It's Intel Atom 330 with 2 GB RAM.
Now my question is:
When server is running nothing but basic install memory comsumption is aroun 500-600 MB.
Today I have rsynced 11 GB of data from one of my VPSs to the ded server and the memory comsumption on the server sky rocketed to 2 GB, leaving only 56 Mb free.
Since a short while back my server memory usage is 100%. The amount of visitors decreased so the memory should be lower in consumption than before.
I suspect a newly installed script could have bugs or misuse of the server by hackers. I don't know how to see on the server what script or what part makes the memory use so high. I see Apache is very high but I'm on VPS. Technical data........
My managed dedicated server at 1and 1 has very low load, but quite slow, I was trying to figure out the reason. The top and free command ( I run at midnight without traffic), here is the result. Can anybody tell me if the memory usage is normal, anything suspicious. Look like the memory usage is high even with no traffic, but 1and 1 support say that's because it's reserved for cache.
