Subject: Re: More OOM problems
Date: Sun, 18 Sep 2016 21:26:14 +0100 [thread overview]
Message-ID: <20160918202614.GB31286@lucifer> (raw)
In-Reply-To: <CA+55aFwu30Yz52yW+MRHt_JgpqZkq4DHdWR-pX4+gO_OK7agCQ@mail.gmail.com>
Hi all,
In case it's helpful - I have experienced these OOM issues invoked in my case via the nvidia driver and similarly to Linus an order 3 allocation resulted in killed chromium tabs. I encountered this even after applying the patch discussed in the original thread at https://lkml.org/lkml/2016/8/22/184. It's not easily reproducible but it is happening enough that I could probably check some specific state when it next occurs or test out a patch to see if it stops it if that'd be useful.
I saved a couple OOM's from the last time it occurred, this is on a 8GiB system with plenty of reclaimable memory:
