Limiting Process Memory Usage
Feb 28, 2007I've been unable to limit the size of a process to keep it from hosing a system. I've tried the following methods:
- RLimitMEM for just Apache (although I'd like this to apply to any process in the system)
- ulimit
- PAM limits.conf (/etc/security/limits.conf)
In theory, either ulimit or limits.conf should do the trick, but when I start up Apache and run a test script to build up some memory, it doesn't get killed off. Is there any way to do what I want? I'll even take kernel modification as an option. We're running CentOS 4.4, but I don't have a problem with swapping out for another kernel.
How Do Find The Memory Usage For Process ID
Feb 22, 2007Few of the processes are getting more meory usage and I checked by using top command.
It is displaying as 0.6% for each process. Does it mean that it is using 0.6% of the total memory?
How can I find exact memory usage?
Yet Another Topic About Process/memory Management
Oct 23, 2007Yet another topic about process/memory management : )
I have a 256 RAM VPS and I need to free up more memory, Im using cpanel and when i use the "top" command, those are the major memory consumers!
PS.: I removed some of the list cause I know i really need them
21635 root 16 0 20888 10m 1316 S 0 1.0 0:01.73 cpsrvd-ssl
13983 root 20 0 14644 8780 348 S 0 0.8 0:00.00 cpdavd
13994 root 34 19 9956 7376 1876 S 0 0.7 0:01.04 cpanellogd
3835 root 15 0 6592 5028 1192 S 0 0.5 0:00.01 chkservd
26595 root 17 0 6652 5020 2816 S 0 0.5 0:00.18 authProg
13911 mailnull 16 0 7664 4972 1544 S 0 0.5 0:00.14 eximstats
13993 root 15 0 6228 4436 1112 S 0 0.4 0:00.03 cpbandwd
13764 root 16 0 3524 1496 628 S 0 0.1 0:00.35 antirelayd
13692 mailnull 16 0 7404 1204 808 S 0 0.1 0:00.22 exim
13698 mailnull 20 0 7404 1144 756 S 0 0.1 0:00.00 exim
18140 mailnull 20 0 7404 1140 752 S 0 0.1 0:00.00 exim
So, my basic question is, which of them I donīt need? SOme of them I know what is it but still have some questions...
1-cpsrvd-ssl , i know this means someone(me) is connected to cpanel, but even if I log out the process stills there, is that normal ?
2-authProg , sometimes there are a lot of those process running, what is that? is that normal ?
3-exim, 3 process running, is that normal ? exim is better than sendmail ?
4-After those questions, which process am I able to drop(and how?) - I only need email forwarding(that is already working), smtp, mysql(already working too), and tomcat server.
IPs Consuming Bandwidth
May 20, 2009My client's site's allocated 10GB/month bandwidth got over run to 12GB so far for this month. Our monthly bandwidth doesnt hit even 2GB.
Fortunately, my host, medialayer, hasnt pulled down the site for overusage of bandwidth.
Looking at awstats,
114.80.100.206 consumed 4.57 GB on May 14th and
114.80.100.207 consumed 5.18 GB on May 15th.
I was told to block the IPs using .htaccess, but this can go on daily from different IPs and I cant simply sit and monitor and block IPs everyday.
Is there some solution to this ? Auto-block when an IP consumes 500MB in day or something similar?
VMWare ESXi 4.0 Network Started Consuming Up To 100 Mbps
Oct 20, 2009I have 4 VMs running on a VMWare ESXi 4.0 server and it was running fine until yesterday when suddenly the network started consuming up to 100 mbps and making everything slow.
I have checked through vSphere and I dont see any VM consuming that much, it only show that the host is using that much.
I am attaching the picture from vSphere.
Consuming Heavy Bandwith Upto 2000 US$+ Per Month
Jun 14, 2008We are facing a very problematic situation since last several months due to accessive bandwith usage. But we are sure this is only local traffic.
We have 2 Servers with our hosting provider
Server A - this is a VPS
all our webfiles/domains/dns/nameservers reside on this server
Server B - this is a dedicated server
contains only databases
(we are actively running vbulletin based forums on this servers)
Since last several months we are facing huge bandwith increase since we have transferred only our databases to Server B. (earlier database + everything was on Server A) We never ever consumed even 50% of the entire allocated bandwith in past when we were on Server A.
But only after moving the database from Server A to Server B we have found this tremendous increase,
Can we do something about same ? as both the servers belong to same hosting provider.
We are not sure but expect that this is only local network traffic between 2 servers.

Cpanel VPS - Plenty Of Free Memory, But 'committed' Memory Exceeds VPS RAM
Jun 12, 2009I 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.

Memory Usage :: Put More Content Into Memory?
Jul 16, 2009I 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

I'm Missing 7 GB Of Ram: Installed Physical Memory 8 GB / Total Physical Memory 1 GB
Apr 4, 2009I 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?

512MB Memory VPS... Out Of Memory Already
Oct 1, 2009I 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:

4. Where is the memory usage coming from (I am finding it very hard to understand TOP)

8 Apache Process
Mar 17, 2008Ive recently installed installed and configured stuff on my new box but after, I realised abnormal memory usage.
Mysql server is taking 256mb, there are somewhere between 6 and 10 apache process taking up at least 40mb each.
Furthermore, when I do: top, I see that the memory usage is increasing by about 120ko each 3 sec.
I am running centos 5.1 and have a load of 0. Basically, there is no one on the server appart from me.
On the server I have at home running debian, I run all thoose thing and it take up 200mb
max.

Business Process
May 13, 2008I'd like to put up here a base question which I hope some will have the goodwill to answer even though it might touch some business secrecies.
We're a gameserver hoster since around ten years, running also vserver products since over two years now. Renting a few Racks in Europe since some time we're a bit in a question mark how rootserver companies deal with the initial hardware costs for every new customer.
Rackspace and today specially power costs are huge cash eaters here in Europe. Dedicated Rootservers are huge space & power consumers per customer ratio. The initial Hw costs for every new rootserver customer might be covered after 4-6 months (if the machine has to be bought newly), adding the bandwidth and power costs it might take up to 8-9 months until a benefit might come in.
Is this the business normality in the rootserver market (waiting 9 months for any benefit, or counting only on the benefit of the 2nd customer using the older Hw), or are the better ways to handle those "initial" costs or keep them affordably low?

Frozen Process
Nov 15, 2007My hosting company is telling me that I have getting frozen processes on my VPS that is causing apache to stop responding.
My VPS is CentOS, with 512 megs of memory and my website is a Vbulletin forum. I have several add-ons installed on vbulletin, and if one of those are causing the problem, how do I figure it out?
When http stops responding, I can access the server with putty on ssh. Running the "top" command, it shows that I still have 100+ megs of memory free and the processor is barely being used.
This has happened twice in just 2 - 3 days. This morning, I asked my hosting company what can be causing this, but no answer so far.
Process Using High CPU
Sep 4, 2007I run a dedicated server, Running
CentOS 4.5 final
Apache 2.0.59
php 4.3.11
MySQL 4.1.20
I have a user who has been importing large sql databases and this causes the cpu to run at 80% - 90% this in turn causes high loads and sometimes causing the server to crash.
Is there a way to automatically limit or control how much the process can use or stop the process to allow the server to recover.
Just trying to put some sort of safe guard in place
