If you can't update your kernel to version 4.4, you need to backport the following two commits: 5cec38ac866bfb8775638e71a86e4d8cac30caae "fs, seq_file: fallback to vmalloc instead of oom kill processes" 0f930902eb8806cff8dcaef9ff9faf3cfa5fd748 "fs, seqfile: always allow oom killer" (the second commit's log message is a bit misleading, I guess the author meant "avoid" instead of "allow") Regards, Matthias >=20 > Matthias Schiffer has been working on a solution: >=20 > https://lists.open-mesh.org/pipermail/b.a.t.m.a.n/2015-June/013339.html= >=20 > Not sure whether he would still be inclined to work on that after the > lack of feedback he had gotten or whether he still has the time > for that. >=20 > Regards, Linus >=20 > PS: How much (free and in total) RAM does your device have, which devic= e is > it exactly?
