[Kernel-packages] [Bug 1303683] Re: Memory resource controller oom killing not functioning

2014-04-25 Thread Glyn Normington
This is not a bug. It turns out the behaviour I was seeing was due to the fact that swap accounting is disabled by default and so the perl process was swapping rather than being killed when its RAM limit was reached. If I turn swap off (swapoff -a), the process is killed correctly. Similarly, if

It occurred to me that the behaviour observed could have been due to an optimisation in a later version of perl, but Ubuntu 13.10 is running perl v5.14.2 whereas RHEL 7 is running v5.16.3. It seems unlikely, therefore, that the version of perl is significant to this problem. -- You received this

Note that the above instructions assuming swapping is off, otherwise memory.memsw.limit_in_bytes would also need to be set to 100. The above testing was done on a 3.11.0-17-generic kernel. Re-testing on an upstream kernel, 3.14.0-031400-generic ("3.14-trusty"), showed the same problem - the pr
