http://www.unix.com – Hi friends, Problem: High memory utilisation of one linux server, due to which a database crashed on the server. My question to all: How does glance calculate that memory utilisation on the linux server is 98%. I mean what components are part of (31.4gb-599mb)? How can i check that myself? Can you please guid me the commands/steps by which i can do that. I want to understand what is taking so much memory and why. Below is the glance (memory) command output and few other command outputs for your reference Code: GSTOMS2 /oravl01/oracle> uname -a Linux indlin706 2.6.18-238.1.1.el5 #1 (HowTos)

I have the following questions regarding Linux memory:

I know that the active memory is the portion of memory which is most frequently accessed. But can someone explain me how linux considers a memory location to be utilised for active memory or inactive memory. What all components does active memory comprises of ?

Hello All,

We have a jave server running on both linux and Solaris environments.

On solaris,it consumes only 600-700MB whereas it goes upto 21G in Linux.

I am monitoring the memory consumption through top command.

Is this high memory consumption expected in Linux?

I have an asp.net 4.o application running on window server 2008 and a oracle 11G database server running on linux. There is two database server with same virtual ip. Recently some how one database server went down and another database server starting working. Every thing went perfectly on database server site with small problem of oracle listener

But on my application server memory start increasi

There are quite number of software running on my server: httpd, varnish, mysql, memcache, java..

Each of them is using a part of the virtual memory and varnish was configured to be allocated 3GB of memory to run.

Due to high traffic load which is 100K, our server ran out of memory and oom-killer is invoked.

I have a Redis server running version 2.4.5 and with a dump.rdb of 11GB loaded into memory. It is running on EC2 on a high memory 4x extra large instance (70GB total memory). However, turns out Redis is already taking up 50GB of memory and is just growing more and more. My dataset is still gonna grow larger, probably to around 20GB, so clearly 70GB memory wont be enough.

clear cache memory 33 weeks 3 days ago

hi all,

i have noticed that my server has 64 GB RAM and i have application in this server but the server has free memory only 15% and utilized 85% however it didn't eat from swap .

does any parameter can be configured in kernel to make the system clear memory from cache like linux

i found this command for linux and it worked it free the memory in redhat i want something like this in solaris ?

I read about Linux and cachd memory at linuxatemyram but there is something that doesn't make sense to me, if the server have even a low load, instead of freeing some cached memory it starts using swap, which makes the server slow..

Even now, when the server load is load average: 0.00, 0.00, 0.00 some memory is swapped while over 85% of the memory is taken for swapping.

I run a windows 2008 webserver and would like to setup the most basic performance monitoring in the world.

A few days ago my linux apache server ran out of memory. The server is a xen guest. The server killed all my processes except ssh.

A minute before it ran out of memory, a script of mine saved the output of various commands.
