783513 - Permaorange Android mochitest-3 OOM caused by dom/indexedDB/ipc/test_ipc.html

Status: RESOLVED INCOMPLETE

(Core :: Storage: IndexedDB, defect, P5)

Description

Bug 778954 and its dependants have been struggling for weeks to get the currently 100% orange (and aborting half-way through) native Android mochitest-3 green again, so we can unhide it. 

For an idea of some of the tests we've tried disabling, look at:
https://bugzilla.mozilla.org/showdependencytree.cgi?id=778954&hide_resolved=0

After all this, m3 is still OOMing, eg:
https://tbpl.mozilla.org/php/getParsedLog.php?id=14368637&tree=Mozilla-Inbound

By chance, on the runs where test_ipc.html were disabled, I noticed we had no OOMs (see https://bugzilla.mozilla.org/show_bug.cgi?id=770046#c17).

With dom/indexedDB/ipc/test_ipc.html disabled on Android, I was able to get a green try run even after re-enabling many of the other tests we'd initially been blaming:
https://tbpl.mozilla.org/?tree=Try&rev=8834b189866b&noignore=1

test_ipc.html runs shortly after the falsely accused tests, so presume we'd just been OOMing before we could update the log - and so why we'd thought it was the other tests instead.

This will get us green again so we can unhide m3 :-)

Mass-closing old bugs I filed that have not had recent activity/no longer affect me.
