Completely disable oom killer
I'm having some intermittent issues that appear to be related to the oomkiller purging some child processes, but I can't see why.
Is there a convenient way that I can suppress all oomkiller activity through sysctl?
I've found some instructions that say these should work, but they do not exist for me.
sysctl -w memory.oom_control=1
sysctl -w vm.oom-kill=0
I have also seen these two being suggested, but the oom killer carries right on.
sysctl vm.overcommit_memory=2
sysctl vm.overcommit_kbytes=0
out-of-memory

You could use /proc/sys/vm/overcommit_memory (see proc(5)), e.g.
echo 0 > /proc/sys/vm/overcommit_memory
as root to disable it. See also the kernel's Documentation/vm/overcommit-accounting
(If you are running an old kernel, consider upgrading it)
