Re: Memory Dump

[Hei Chan <structurechart@yahoo.com>]

Never used massif before.  Just tried it for few hours, and it doesn't seem like to be able to take snapshot when a user requests for/signals to.

I had to instrument my code to malloc big chunk of memory in a predefined time (i.e. sleep(x)) and deallocate later to trigger a snapshot to "stamp" the "times".

A quite useful tool tho, but I am not on 3.7.0 yet that offers pages-as-heap=yes option; and it shows nothing too fishy to me yet :(

Very appreciate your input tho.


Cheers,
Hei

Hi,

I am not sure, but it seems massif (the tool from the valgrind 
toolchain) could help you.

P.S. However the question is still interesting - is there a possibility 
to solve the problem with gdb? Could someone answer it?

Anton.
