Comment 16

[Andrew McCreight (out of office until 8/21) [:mccr8]]

This looks like a variation of bug 1576498 where we leak some extra stuff. Hopefully it will also be fixed by bug 1612364.

Comment 17

[Andrew McCreight (out of office until 8/21) [:mccr8]]

I'll assume this is fixed for now.

Comment 18

[Alexandru Michis [:malexandru]]

Andrew, since the patch from https://bugzilla.mozilla.org/show_bug.cgi?id=1628052#c11 landed, I think this issue has reappeared:
https://treeherder.mozilla.org/logviewer.html#/jobs?job_id=300018291&repo=mozilla-central&lineNumber=8397

Should we reopen this bug?

Comment 19

[Andrew McCreight (out of office until 8/21) [:mccr8]]

Yeah, that makes sense.

Looking at what is leaking, maybe nsIdleService is keeping other stuff alive.

Comment 20

[Andrew McCreight (out of office until 8/21) [:mccr8]]

My guess would be that some JSM creates a new idle service after we start shutting down, and whatever existing code there is to stop this is failing to catch this case. Given how rarely this happens (0-1 times a week), it doesn't look like a high priority.
