I am repeatedly seeing errors like

on a few servers

The servers have enough memory free and the swap usage is 0, yet somehow
the kernel denies the posix_memalign with ENOMEM ( this is what I think is
happening!)

The numbers requested are always 16, 16k . This makes me suspicious

I have no setting in nginx.conf that reference a 16k

Is there any chance of finding out what requests this and why this is not
fulfilled
