> When recovering executors with a tracked pid we first try to establish a connection to its libprocess address to avoid reaping an irrelevant process:

> If the connection fails to establish, we should not track its pid: https://github.com/apache/mesos/blob/4580834471fb3bc0b95e2b96e04a63d34faef724/src/slave/containerizer/docker.cpp#L1071
> One trouble this might cause is that if the pid is being used by another executor, this could lead to duplicate pid error and lead the agent into a crash loop:
