syslog-ng invoked oom-killer in __inet6_check_established

[Marc Burkhardt]

Hi there,

while downloading a few new kernels (don't know if that is related, however),
the following trace appeared. I'm relatively new on the 4.5 series but such
thing actually never happend on my former 3.12 installs. Is that somehow related
to vm_swappiness==0 on the 4.5 (or: after 3.12/3.14) kernels?

What I did was just

wget -cS https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.5.5.tar.xz https://cdn.kernel.org/pub/linux/kernel/v4.x/linux-4.4.11.tar.xz https://cdn.kernel.org/pub/linux/kernel/v3.x/linux-3.14.70.tar.xz

Thanks anyone for a hint!

Regards,
Marc
