---------------------------------
Summary: Processes can be stuck in D state and block destroy
Key: MESOS-2421
URL: https://issues.apache.org/jira/browse/MESOS-2421
Project: Mesos
Issue Type: Bug
Components: isolation
Affects Versions: 0.21.1
Environment: CentOS, 3.10 kernel
Reporter: Ian Downes
We've observed processes getting stuck in D state (uninterruptible sleep) when
using the cpu isolator. This prevents the MesosContainerizer launcher from
killing all container processes and blocks destroying the container.
It appears to be a kernel scheduler bug: the processes can be unstuck by
modifying the cpu.cfs_quota_us for the cpu cgroup. This seems to run the
processes, deliver the kill signal, and they exit.
We should implement this workaround in the launcher destroy path when processes
are observed to be in D state.
