Comment 1

[amarc]

hey Emilio , could this be caused by bug 1999050?

Comment 2

[Emilio Cobos Álvarez [:emilio]]

I don't see how. Seems an issue with the ml code. Tarek, Paul, any recent change that could've caused it?

Comment 3

[agoloman]

Hi! Could you please take a look at these failure? Backfills shows that it is regressed by Bug 1997192.

Comment 5

[Matthew Gaudet (he/him) [:mgaudet]]

So I previously worked around a worker lifecycle issue with LlamaStreamSource during shutdown; that was what gave me the confidence to turn it back on, but it appears that we're still seeing issues. See Bug 1996263 for details.

Ultimately I can't make the call for whether or not we should pull the MTQ enablement patch; While I could address the proximate cause here by adding more checks, it's not really sensible to keep pulling on this thread forever -- Bug 1996263 is the answer.

Comment 6

[Matthew Gaudet (he/him) [:mgaudet]]

(Oh, to clarify: what we do is going to depend entirely on the capability of the ML team to work with the DOM/DOM LWS teams to figure out lifecycle fixes)

Comment 7

[Matthew Gaudet (he/him) [:mgaudet]]

(the incremental step patch one could write would be to reload JSContext* as part of the loop header here and bail if JSContext goes away during loop processing.)
