Hello,
I am running a P2P related server, which has many connections to it at one time (about 100,000 at peak times). But I have been getting
eserver invoked oom-killer: gfp_mask=0xd0, order=0, oomkilladj=0 errors followed by
Out of socket memory
I believe this is related to rmem, but I am not sure. Here's my current net related sysctl settings
