The bug
Using /setidletimout with high values instantly kicks the players. It is in some cases only possible to disable this from the server console or with an NBT editor. Based on MC-38058 the command should at least not allow such high values.

No problem. As normal user you cannot close reports, only mods or developers can do that. On this bug tracker we (try to) distinguish between "duplicates" and "clones". Clones is often used when the original bug was successfully fixed but reappeared or the circumstances changed, in this case the command changes in the latest snapshots, and the existing report is already resolved. A report being a clone of another one remains open because there is often no point in reopening the old report.
But as normal user you do not really have to care about this distinction. It is rather important that you avoid creating duplicates. In this case you could have commented on MC-38058, but it is fine the way it is now.
Clones MC-38058, but now with the command changes invalid values like these should not be allowed in the first place.
