--- Comment #2 from dieter ferdinand <dieter.ferdinand at gmx dot de> ---
hello,
i try to get help from gentoo, but they can' help. you can read the bugreport
here: https://bugs.gentoo.org/show_bug.cgi?id=613304

it seems, the problem is, that more then one process get the message "no free
memory" or "out of memory" if one process need much memory in a short time.

after the problem happens again, i try to find some reason for the problem and
i see this:
1. chromium crashed with many open windows while i open more windows.
2. at the same time some other programs (wine,firefox, ...) which try to get
memory will crash at the same time
3. the amount of free memory is at this momen less then 500 MB, the available
memory is over 10 GB
4. after i close more then 10 tabs in chromium i can reload it and open some
new windows without crash chromium imediadly

it seems, that at the most time, this problems happens, one program need to
much memory or need much memory in a short time because chromium runs over 10
seconds before it crash again after a restart so i can close some tabs before i
must restart it again.

before i update my system i use chrome with 32 bit and i have much more windows
open as in chromium. after the update chrome crash to often so i can't use it
again.

there are some important questions:
- how can i check how many real memory chromium needs and is this memory
reserved for the masterprocess or the threats or subprocesses and how many
memory can a process use in this different situations ? i don't know!
- why can't other process allocate memory if one process runs in out of memory
while it is a 32bit process?

normaly every process should be able to use 2 GB or more memory without making
problems, if one process will get to much memory.

i think, tghis must be a bug, but i don't know where. i think glibc or kernel.

goodby
