------------------------------------------

> Project: Mesos
> Issue Type: Bug
> Components: master, slave
> Reporter: Benjamin Mahler
> Labels: reliability, repair
>
> On Linux systems, when a soft or hard CPU lockup occurs on slaves, we have observed strange and undesirable things occur possibly due to kernel bugs.
> With root access and {{sysctl}}, it should be possible to configure an automatic reboot of the machine when a soft/hard lockup occurs:
