app that can cause the problem
Run this app with ./progOLN 20000000 100
and it will cause the problem. Increase the first number if memory is not fully
used up by these parameters.
if those apps are misbehaving when theres a shortage of memory, the bug lies with those apps, not with the kernel. resource starvation issues are fixed typically by setting reasonable ulimits. The kernel can overcommit resources, but if you design a pathalogical case to actually use everything, breakage is to be expected. I think the problem is that I shouldn't have classified it under "kernel". The bottom line is that any user can make the system permanently unusable (until it is restarted) simply by accidently (or intentionally) making an array that is too large and writing to it. If this is a GNOME bug then I am of course happy to have it classified there. It does certainly seem like something that needs attention however. |
