Package: collectd Version: 5.4.1-3 Severity: important Tags: upstream Hi,
The documentation suggests that exec plugins (typically scripts) should be long-running processes that output metrics at a suitable frequency, rather than being re-executed every time a new metric is required. Unfortunately, collectd does not kill its children when it quits, leaving these long-running processes running (they will eventually get broken pipe on their stdout, but that might well take a long time). Particularly, if you restart collectd, you end up with multiple copies running. Collectd must know which children it has spawned, so it should clean up properly then exiting.
