Description

[Ed Morley [:emorley]]

20:55	NeilAway	is it known that pending jobs can show as overdue?
20:56	camd	NeilAway: do you have an example of a job I could look at?
21:01	NeilAway	camd: 8e21737b6ff7
21:01	camd	NeilAway: is that mozilla-inbound?
21:03	NeilAway	camd: try
21:06	camd	NeilAway: yeah, I think that can happen when the machines are quite busy. We do our best to predict how soon a job will complete based on past jobs of the same type. But sometimes it can take a long time for a job to start running if the machine load is high.
21:07	camd	that being said, if this seems like it's off-base, then please do file a bug and we'll take a look at it. :)
21:09	NeilAway	camd: well, surely you should only start predicting the completion time once the job has actually started?
21:13	camd	NeilAway: I *think* the dev on that had tried to predict based on the time it took a pending job of that type to get all the way through to completion. I'd have to double-check.
21:19	camd	NeilAway: yeah, it looks like he calculates an average based on the time, which will include the time to start. But that time can vary a fair bit depending on infrastructure load.
