Title:
Kernel fails to execute code for killing OOM task if
oom_kill_allocating_task = 0
Status in “linux” package in Ubuntu:
Fix Released
Bug description:
The problem is thoroughly described in this question:
http://askubuntu.com/q/398236/20275
Steps to reproduce:
Make sure oom_kill_allocating_task = 0 (it's the default configuration)
cat /proc/sys/vm/oom_kill_allocating_task
echo 0 | sudo tee /proc/sys/vm/oom_kill_allocating_task
Disable your swap to make the test faster.
Fill your RAM.
After that the machine will freeze completely forever spinning HDD for some reason and thus slowly degrading it.
