How to immunize a process from the OOM Killer

[Juan Miscaro]

Hi, I'm running 2.6.24 on Ubuntu.

I've got a OOM Killer gone wild.  I have plenty of free memory (over
40 GB) and lots of processes are being murdered.  Anyway, I would like
to first prevent a few processes from being killed in the hopes of
buying me time (users can work) to discover why the killer is being
invoked in the first place.

I've read in a few places [1] that in order to immunize a process you
need to modify the value of /proc/PID/oom_adj.  Thing is, such files
cannot be edited directly.  How do I achieve my goal?

Thank you,
