Hello guys, I am implementing a mesos executor and see this behavior when I enabled cgroups isolation. It seems the slave got oom killed. I didn't expect the slave to be oom killed in any circumstance, am I wrong?
Here are the slave log: I0822 21:22:09.168122 15557 cgroups_isolation_module.cpp:440] Launching jobsystem (/net/ hsljin.aoa.twosigma.com/userhome/ljin/cvs/JOBS-MESOS/ts/jobsystem/sbin/jobagent-c dev) in /tmp/mesos/slaves/201308201743-164210880-5050-16120-10/frameworks/201308201743-164210880-5050-16120-0046/executors/jobsystem/runs/9a3c2f9f-733b-4c68-a269-2f7f17d6ad06 with resources for framework 201308201743-164210880-5050-16120-0046 in cgroup mesos/framework_201308201743-164210880-5050-16120-0046_executor_jobsystem_tag_96193e04-40d2-4911-9a68-6eb86c534f97 I0822 21:22:09.169131 15557 cgroups_isolation_module.cpp:572] Changing cgroup controls for executor jobsystem of framework 201308201743-164210880-5050-16120-0046 with resources I0822 21:22:09.169831 15557 cgroups_isolation_module.cpp:801] Started listening for OOM events for executor jobsystem of framework 201308201743-164210880-5050-16120-0046 I0822 21:22:09.170280 15557 cgroups_isolation_module.cpp:469] Forked executor at = 22708 I0822 21:22:10.583222 15559 slave.cpp:487] Got assigned task 1 for framework 201308201743-164210880-5050-16120-0046 I0822 21:22:10.583271 15559 slave.cpp:523] Queuing task '1' for executor jobsystem of framework '201308201743-164210880-5050-16120-0046 I0822 21:22:11.730157 15555 slave.cpp:762] Got registration for executor 'jobsystem' of framework 201308201743-164210880-5050-16120-0046 I0822 21:22:11.730293 15560 cgroups_isolation_module.cpp:572] Changing cgroup controls for executor jobsystem of framework 201308201743-164210880-5050-16120-0046 with resources cpus=2; mem=2048 I0822 21:22:11.730443 15555 slave.cpp:820] Flushing queued tasks for framework 201308201743-164210880-5050-16120-0046 I0822 21:22:11.732163 15560 cgroups_isolation_module.cpp:775] Updated 'memory.soft_limit_in_bytes' to 2147483648 for executor jobsystem of framework 201308201743-164210880-5050-16120-0046 I0822 21:22:12.398077 15558 slave.cpp:1194] Killing executor 'jobsystem' of framework 201308201743-164210880-5050-16120-0045 I0822 21:22:12.398149 15559 cgroups_isolation_module.cpp:535] Killing executor jobsystem of framework 201308201743-164210880-5050-16120-0045 I0822 21:22:12.398381 15561 gc.cpp:97] Scheduling /tmp/mesos/slaves/201308201743-164210880-5050-16120-10/frameworks/201308201743-164210880-5050-16120-0045/executors/jobsystem/runs/5c9cddd0-7b4c-464b-9b2d-17e8197970a1 for removal Killed
