Description

The endpoint /monitor/statistics.json of a slave reports inaccurate data after restarting the slave process.

For example, the mem_rss_bytes field of a task reports a value of about 200MB before the restart. After restarting the slave, the task is reported to use 42MB and that value does not change over time.

All tasks use the Docker containerizer.
