Memory/data -last time I promise
I've seen several posts over the past 2-3 weeks about memory issues. I've
tried to carefully follow the suggestions, but remain baffled as to why I
can't load data into R. I hope that in revisiting this issue that I don't
exasperate the list.
The setting:
1 gig RAM , Linux machine
10 Stata files of approximately 14megs each
File contents appear at the end of this boorishly long

XEN server stalling .. problem spotted - solution required
Ok, I''ve been chasing this for many days .. I have a server running 10 instances that periodically freezes .. then sometimes "comes back."
I tried many things to try to spot the problem and finally found it by accident.
It''s a little frustrating as typically the Dom0 and One (or two) instances "go" and the rest carry on .. and there is diddley squat when it

Wine Hides On-board RAM
I have recently noticed an unusual side-effect of running Wine. When I
first start up my system, /proc/meminfo reports MemTotal as 256892 kb.
After running Wine for awhile, /proc/meminfo reports MemTotal as 32680
kb. The system performs as if it only had 32 MB of RAM. A reboot of
the system resets total memory to the proper value.
My question is:
1) Has anybody else encountered this?

how mem-set / balloon changes totalram_pages
Hi,
I find that after I use xm mem-set to change the current memory
allocation of a dom, the MemTotal in /proc/meminfo will give the
current allocation.
In my understanding, the balloon driver simply alloc / free pages, so
the MemTotal should not be changed. Only the free memory will be
affected.
In normal linux, the value of MemTotal comes from "totalram_pages"

Bug#734761: xen-system-amd64: "XEN kernel detects 3GB RAM instead of 4GB"
Package: xen-system-amd64
Version: 4.1.4-3+deb7u1
Severity: normal
The xen kernel detects 3GB of memory instead of the full 4GB. When using the "normal" kernel 4GB is detected.
On boot the 4GB is detected:

Kernel memory initialisation
Hi,
I have a small problem on small (128Mo) PV DomU : the kernel use too
much memory.
By default if I start my DomU kernel (2.6.39.3) with "memory = 128" in
the xmdomain cfg, I obtain only 54MB of usable memory :
# head -n 1 /proc/meminfo
MemTotal: 54844 kB
While searching, I found that Xen (I guess) annouce 4GB of ram to the
kernel, so in logs I have :

ext3 buffer leak/memory leak?
Hi,
I am a new ext3 user and I am having some problems. I seem to have
introduced a memory leak after adding ext3 support to the kernel. I noticed
when running top or viewing /proc/meminfo my free memory pool seems to be
decreasing while my buffers are increasing (around the same rate). I am
currently using a root partition and a /var partition. I have listed the
ext3 boot messages below.

Restriciting memory usage for samba using Cgroups
Hi
Currently we are using cgroups to limit samba memory usage on our target
we have limited the memory to 20MB and we are able to see samba is
restricted to it.
With this we are able to restrict the cache memory to ~34MB (never goes
beyond this)
BUt issue we arere facing is the Buffers are increasing gradually and it is
not able to restrict.
Commands Used to restrict memory on target:

centos6 and xen4 dom0 memory allocation
Hi,
This is slightly OT as xen is not officially supported in EL6. But
maybe someone else is running it on centos6 as well and could help me
out here:
I have problems allocating a static amount of memory for my xen dom0.
It seems to reduce when new domUs are created, even though I *think*
ballooning is disabled. Can someone advise me what I'm doing wrong?

Now reporduced with 100%
1) create contrainer with memory limit 1Gb
2) run inside simple memory test allocator:

#include <unistd.h>
#include <memory.h>
#define MB 1024 * 1024
int main() {
int total = 0;
while (1) {

ramfs to tmpfs
Hello,
I was using a bunch of cpios in initramfs as a working system, and
wondering why the unused files weren't being paged out to swap.
So I reread ramfs-rootfs-initramfs.txt and now I know.
So I wrote the attached utility. It creates a tmpfs, moves all files
on the initramfs, moves / and executes the real init.
It works, even with hardlinks, but it isn't the correct approach. Have
