[Deploying Sakai] linux tuning

I've found it useful to adjust the kernel oom killer behavior. (

To the guides recommended settings of
vm.overcommit_memory = 2
vm.overcommit_ratio = 80
appear to be more stable.

OOM killer didn't happen very often, but it was very annoying when it did
happen. A lot more often when users had active terminal sessions open on the
same machine.

That and the file descriptors are typically all I've heard of. Would also be
interested in other tips.
