Description
During internal tests it appeared that dd process get killed by OOM-Killer when it belongs to a cgroup with memory enforcement.
In our scenario we use dd to write 10G file:
dd if=/dev/zero of=./testing bs=1M count=10000
Parent shell belongs to a cgroup with memory limit set to 1.5GB
Our tests on local filesystems and GPFS were fine - no oom killer invocations have been seen. Only Lustre operations tend to fail due to memory excess
I'm attaching oom details from dmesg
