[Henrik Skupin [:whimboo][⌚️UTC+1]]

Could someone please backfill on mozilla-inbound so we can see when this failure exactly started?

Comment 4

[Marco Castelluccio [:marco]]

Let's see what the backfill says.

Comment 5

[Henrik Skupin [:whimboo][⌚️UTC+1]]

The assertion for `pages_.empty()` is bug 1485983.

Comment 6

[Andreea Pavel [:apavel]]

Hi Henrik. I'll look into this and see what i can find out. 
Will keep you posted.

Comment 7

[Jan de Mooij [:jandem]]

See bug 1486101 comment 3. We seem to be leaking GC things at shutdown, hopefully retriggers will help narrow it down.

Retriggers ended up here: https://tinyurl.com/y9lwqfy3

[Andreea Pavel [:apavel]]

Kris, based on the results in Comment 8, this failure occurred started somewhere in between this range: 

https://treeherder.mozilla.org/#/jobs?repo=mozilla-inbound&filter-resultStatus=testfailed&filter-resultStatus=busted&filter-resultStatus=exception&filter-resultStatus=success&filter-resultStatus=pending&filter-resultStatus=running&filter-searchStr=windows10-64-ccov%20debug%20firefox%20functional%20tests%20(local)%20with%20e10s%20test-windows10-64-ccov%2Fdebug-firefox-ui-functional-local-e10s%20fxfn-l-e10s(en-us)&group_state=expanded&fromchange=e3bbdb2f97fed1fbdb74b2e15ecb3170ee490780&tochange=eef3785a6b441e83d392c2569091e969e1eac658

Since the retriggers for Bug 1484373 the failure is different, i would assume this is caused by Bug 1484496.

Can you please take a look and give input? 

Thank you

The problem is that we have two identical bugs here. Bug 1486101 got filed right after this one, and all failures are getting classified against it.
