Subject: [RFC] 3.10 kernel- oom with about 24G free memory
Hi all,
I get an oom on a linux 3.10 kvm guest OS. when it triggers the oom
it have about 24G free memory(and host OS have about 10G free memory)
and watermark is sure ok.
I also check about about memcg limit value, also cannot find the
root cause.
Is there anybody ever meet similar problem and have any idea about it?
Any comment is more than welcome!
Thanks
Yisheng Xie
