http://serverfault.com – 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. Here was the output: # free -m total used free shared buffers cached Mem: 2003 1866 137 0 3 1159 -/+ buffers/cache: 703 1300 Swap: 511 0 511 # vmstat 1 2 procs -----------memory---------- ---swap-- -----io---- -system-- ----cpu---- r b swpd free (HowTos)

Stories similar to Linux server ran out of memory stopped everything except ssh and swap was unused

I'm operating a little storage server on debian, over the past months I've noticed the process udisks-daemon eating up almost all available memory.

Is this just really aggressive caching or a memory leak?

we have a server with 8GB, running mysql, 4 java applications and a small postgres db.

I am running centos 5.8 with cpanel. Lately I am getting reports that my swap is full , but there is a lot of free memory to use.

Linux server slow. Why? 3 years 22 weeks ago

I have been getting requests from application teams that the server is running slow. I have checked the memory utilization, processes running and cpu utilization. Please find below:

#free -m total used free shared buffers cached Mem: 3006 2994 11 0 6 171

can anyone tell me where the memory is gone: (no, this time neither buffers nor cache)

I have VPS server with 1.25GB ram and 0.51GB cache trying to up an e-commerce website with 200k items, db now is about 2gb anything is now works terrible slow now because of lack memory mysql queries takes about 30 seconds to complete on the peak memory usage.

Critical Memory 46 weeks 6 days ago

My Redhat server shows the following:

free -m ============= total used free shared buffers cached Mem: 8113 8078 35 0 171 6491 -/+ buffers/cache: 1415 6698 Swap: 8189 59 8130

Is 35 mega of free memory considered critical on a production server ?

Can you help me understand what is taking memory on my linux box?

When I run free command I see the following picture (14GB are used, 10GB are free):

I have an issue where when I try to build a really large project, my machine starts swapping (several GB) even though there's plenty of memory (14 GB in fact).
