[gentoo-user] OOM memory issues

[James]

Hello,

Out Of Memory seems to invoke mysterious processes that kill
such offending processes. OOM seems to be a common problem
that pops up over and over again within the clustering communities.


I would greatly appreciate (gentoo) illuminations on the OOM issues;
both historically and for folks using/testing systemd. Not a flame_a_thon,
just some technical information, as I need to understand these
issues more deeply, how to find, measure and configure around OOM issues,  
in my quest for gentoo clustering.


Also, I posted a bug to add Ftrace/trace-cmd/kernelshark
to gentoo's ebuilds. They are looking for a maintainer for
this *wonderful* new_age kernel tool for Function Tracing.
It's a wee_bit out of my league (really?) so anyone wanting to
create an overlay, would be fantastic. There's lots of links
in the bug report; even videos to see what it can be used for.


Bug-517428

All information is welcome. Please, no flames.

James
