Hi everyone,
I am having issues with the cgroups isolation of Mesos. It seems like
tasks are prevented from allocating more memory than their limit.
However, they are never killed.
I am running Aurora and Mesos 0.20.1 using the cgroups isolation on
Debian 7 (kernel 3.2.60-1+deb7u3). .
Maybe a newer kernel might help? I've poked around for some suggestions
on the kernel-configuration file for servers running mesos, but nobody
is talking about how they "tweak" their kernel settings, yet.
Here's a good article on default shared memory limits:

Also, I'm not sure if OOM-Killer works on kernel space problems
where memory is grabbed up continuously by the kernel. That may
not even be your problem. I know OOM-killer works on userspace
memory problems.
Kernelshark is your friend....
hth,
