> As promised, here's the patch to protect a process from being killed when > pageout is in memory shortage. This allows a process to specify that it Just in case, anyone gets interested, here is another one I made about two years ago for our own needs (mass web-hosting, etc.) http://www.blackflag.ru/patches/vm_pageout.c.diff :) Allows to specify "safe" process(es) names in a sysctl variable. Doesn't touch root processes (that's what I needed as well) and sends SIGKILL if process is not willing to terminate. I recall Matt Dillon had some very useful comments about the possibility of further development of such features. Like some preferences of what processes to kill first (some other criteria in addition to the process size). -- Andrey Alekseyev. Zenon N.S.P.
