Deployment xxxx of type NewDeployment for group xxxx failed error: process start failed: failed to run container sandbox: container_linux.go:344: starting container process caused "process_linux.go:424: container init caused \"mask path /proc/latency_stats: permission denied\""

This is a known issue and there is a PR in the works:
