Is there a program for linux that exists to troubleshoot memory allocation problems?
I am bound and determined to get this to work..I think I need a new direction..a new tool to use to figure out what's going wrong.
This is on a vps server...yet I feel this post belongs here..since this is extremely technical in nature.
I have already become an expert of kernel settings...and that really has not helped terribly.
I got this from a client I host:
We get this message on our forum (arcade section)
Fatal error: Allowed memory size of 8388608 bytes exhausted (tried to
allocate 131375 bytes) in
/home/XXXXX/public_html/forums/sources/classes/class_display.php on line 482
Before I look into that, is it a server problem (my responsibility), or a problem with the client's forum software (not my responsibility).
If it's something I have to fix from my end, what do I do? I've never encountered that error that I can remember.
I just signed up to a new VPS server with 640MB RAM guaranteed and 2GB burst RAM..
Here's what I've got on my privvmpages:
Soft Limit: 524,288
Hard Limit: 655,360
I stumbled upon this thread (webhostingtalk.com/archive/index.php/t-466457.html) and realized that I only get 512MB guaranteed RAM instead of 640MB RAM as written on their specs..
Is my calculation all right?.. or did I miss something here..
I am running exim, centos.
My mail server stopped working this weekend, when I got in today I restarted and all the emails came through. The panic_log shows:
daemon: accept process fork failed: Cannot allocate memory several times over the course of a few minutes. Can anyone give me advice on troubleshooting this one?
How could I check the amount of CPU allocation I have on my VPS
Currently I have a VPS 1GB 50%CPU,
not what I would say is fast or can do sitemapping, I would like to be able to benchmark, as my small vps seems better and is 1/3 of the price
Q1: You've got one server with 8MB RAM. You offer a single VPS plan with 256GB guaranteed RAM. Does this mean that you are limited to exactly 32 VPS clients on this machine? (Or 8 clients if you had a single 1MB plan.)
Q2: On a single Virtuozzo machine, again with 8MB RAM, do providers typically mix and match plans on the same box? In other words will they typically put their 1MB clients on the same box as the 256MB clients?
I just moved data centres here in the UK. I've paid for a 47U rack with 8amps of power. I plugged everything in and the meter is reading 8.9 - 9.1 amps. Seems fine at the moment, should I be worried about it tripping or is it just a case of if they find out they'll hike my bill up?

I was unziping from network 4gb file to my server and server crashed. When I got it back up partition has allocated 4gb of space, but there is no file I cannot reallocate it.
/dev/hda6 67G 63G 437M 100% /home
Like you can see above 4gb is allocated but it is not used, so what can i do?
Our company currently has colo in NY, UK and Geneva and have recently started to rent some space in an Australian datacentre.
In each of our existing centres we have a /26 range of IP addresses assigned to us (62 usable IPs) and we requested the same for our Australian installation.
The colo company has email us today with our IP range allocation and they seem to have chosen to allocate us 12 seperate /29 ranges (6 usable IPs).
This seems really strange to me, is it normal practise? Why not just assign us one /26 as requested.
Also, our WatchGuard firewalls only accept one range in the configuration and then you add in all of the IP aliases seperatly. If I set a the IP range to bigger than the range we own (to cover all 12 seperate ranges we've been issued) would this cause problems for the people that own the other IPs in this large range?
Got a slight problem on my development OpenVZ server, it has been working 100% up until 2 days ago when I did a restart.
I have 5 VE's (id 201 - 205), I was able to run all 5 will ample resourses spare.
Now I can only run one at a time...?
I checked the logs and get this
Dec 3 18:16:17 localhost kernel: allocation failed: out of vmalloc space - use vmalloc=<size> to increase size.
Dec 3 18:16:17 localhost kernel: VE: 202: stopped

Im getting this error when i try to create a package for a client. As far as i can tell, everything is set up properly. Its located inside my WHM area, but the billing software wont create the account and gives me:
Package Not Allowed or Exceeded Resource/Account Allocation
but i have no resource or account allocation settings set. everything is wide open.
My second question is, if i want to give someone unlimited bandwidth/storage, how do i do that? ive tried -1 and 0, but it keeps kicking it out as not valid. any ideas?

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.

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 just ordered a server from serverbeach that should have come with 2 GB but I see that this one comes with 8 GB
Unfortunately, I seem to be missing 7 GB of ram.
Installed Physical Memory: 8 GB
Total Physical Memory: 1 GB
Windows 2008 Server Web 32-bit
Now, being a 32-bit system, I should see 3-4 GB of ram right?
Any idea why only 1 GB is available for the OS?

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?

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
How much extra memory do I need on a VPs to be safe ?
Do I need something like 20% more of what I actually use just to be safe?
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.
View 4 Replies View RelatedI'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.
Mem: 196608k total, 82972k used, 113636k free, 0k buffers

I noticed that, VPS with Xen technology, are using up far more memory than others?
Lets say, I usually use about 300mb of ram in a VPS with openvz, but VPS with xen, with the same usage, is using about 820mb of ram.
Even without running anything...after a fresh install of centos 5, with only few OS processes, its using around 170mb of ram already.
Is this so with Xen? The expected ram usage with Xen? Or am I missing something?
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?
never got this yellow status on the old VPS.
if someone here could offer their advice/expertise in this problem. I have a 256MB CPanel VPS. When Apache is restarted, memory is around 180MB which is perfect
However, before long, memory usage is at 240MB. Looking at top processes, this is the top 5 i get...

Anybody able to offer any advice? I see that all processes are httpd, is lighthttpd or lightspeed a solution?
The main site serves up php content (No mySQL) and a few images. It also has a LOT of image requests which are redirected by photobucket via .htaccess.
The secondary site on the server (not yet launched) is going to be an arcade site running gamescript. I have been hesitant to release this site untill these memory issues are sorted.
My VPS Service Status showing
Memory Used 70.4 %
is that normal? how I can less memory used.

Second I just got following email from system
"The following list of files have FAILED the md5sum comparision test. This means that the file has been changed in some way. This could be a result of an OS update or application upgrade. If the change is unexpected it should be investigated:
/usr/bin/sa-learn: FAILED
/usr/bin/sa-update: FAILED
/usr/bin/spamassassin: FAILED
/usr/bin/spamc: FAILED
/usr/bin/spamd: FAILED"
any issue with server?
I have got a VPS with slhost but seems like I am hitting my memory limit when I check in VZPP.
Is there anyway I can find out which websites are causing high loads etc and get the limit back to normal?
