Re: How to find out where memory leaks to

[Thomas De Groote]

On the box I was talking about:

on another box, same symptoms (ext2 disks, no quota) :
[EMAIL PROTECTED]:~$ free
             total       used       free     shared    buffers

Swap:          486          0        486

The second 'free' was a couple of hours later, without touching the 
machine...

Thx,

Hey,

I am running a quite standard Debian woody setup with the kernel 
2.4.18
that comes from the packages. The 2 HDs are in a RAID0, formatted as
ext3, with quota installed. Problem is that for some reason after 
about
1 week the 1 Gb of RAM is completely filled and when looking in top or
ps I can't discover any process taking a lot of RAM.

Does anyone have an idea as to how to find what is taking my memory
away? I could add another Gb, but I guess that will be taken in soon 
as
well...

Sorry if this is a newbie-question answered elsewhere, I did a search
but couldn't find anything.
Can you send us the output of "free -m"?  Mine looks like this:

             total       used       free     shared    buffers     
cached
Mem:           250        238         11          0          0         
53
-/+ buffers/cache:        185         65
Swap:          899        453        446

I only have 11MB free, but that's because my kernel has 53MB stashed
away as disk cache.  You want to look at the second row (-/+
buffers/cache:) to get a useful value for your free memory.  When an 
app
needs more memory, the kernel will flush the cache and a program can 
use
the memory.
