Memory monitoring

Memory monitoring

[Klein, Bernhard]

Hi all,

I need to do a memory-monitoring inside my developed binary, because I have
an memory leak inside it and I can't localize it. So my idea is, a
monitoring over a couple of days/weeks. I can't use any third-party tools to
do this, because the binary works in an production environment.

How can I do this on an easy way? (is any Sourcecode available ?)

I need this under Solaris 9 and under SuSE Linux (maybe there is no
difference between both plattforms). I'm using gcc 3.3.2

Hi Bernd,

>How can I do this on an easy way?

The easiest way to do it is to test for memory leaks in a test (non-production) environment.

In that way, you can instrument the code any way that you find appropriate.

You can even replace the memory manager with one of your own devising.  Or some third-party memory manager, that has facility for tracking memory leaks.  Such as the ones from <http://www.rational.com/>, the IBM Rational Suite (Purify, Quantify, et al).

HTH,

Test early.  Test often.

Hi,

If you're running Linux on an x86 platform, you might want to give Valgrind
a chance to look at your code. (http://valgrind.kde.org/). It's worked
wonders for me. You can run the lightweight memory checker on your
production code, if performance isn't really critical (you'll have to
compile with debugging symbols though, in order to be able to use its
output). Unfortunatelly, Valgrind won't run on any other platform, due to
the way it's designed (it's actually a CPU emulator).

Hi,

don't know exactly if this a help for you, but if you're on
x86 "valgrind" could maybe be of help for you?

Torsten.

As Eljay said, there's Purify:

    http://www-306.ibm.com/software/awdtools/purifyplus/unix/

Last I looked (when it was still Rational) it cost $2,800 or thereabouts for
a unix licence. But we fixed all our bugs in the free trial period :-)

Looks like they still offer a free trial :-) If you can't exploit that, I'd
still check your code on linux - assuming you're running 32-bit code on
Solaris there won't be a lot of changes in your memory management code.

Have your tried "electric fence"?
