Description

[Liz Henry (:lizzard) (relman/hg->git project)]

This bug was filed from the Socorro interface and is
report bp-4d047037-63f8-4ca4-b906-ce6bb0180705.
=============================================================


The crash volume in beta 62 looks higher than it is on release 61, which makes me think this may end up as a top crash on 62 release.  Often a startup crash.

I should correct that, the volume isn't higher but the rate is high (it's the #11 top crash in beta)

Comment 2

[Andrew McCreight [:mccr8]]

Looking at 62b3, b4 and b5, 54% of the crashes have the reason "MOZ_CRASH(IPC FatalError in the parent process!)", 44% have IPDL error: "Error deserializing 'data' (SerializedStructuredCloneBuffer) member of 'ClonedMessageData'". abort()ing as a result and 1.62% have "IPDL error: "unknown union type". abort()ing as a result."

Comment 3

[Jed Davis [:jld] ⟨⏰|UTC-8⟩ ⟦he/him⟧]

Error deserializing 'data' (SerializedStructuredCloneBuffer) member of 'ClonedMessageData' (the error the crash linked in comment #2) is a different error from the one in bug 1562616 comment #0.

As comment #2 reflects, this crash “signature” is not specific enough to be useful.

Comment 4

[Jens Stutte [:jstutte]]

Aggregating over MOZ_CRASH_REASON leads to:

Reason	#	Percentage
MOZ_CRASH(IPC FatalError in the parent process!)	786	83.53 %
IPDL error: "Error deserializing 'data' (SerializedStructuredCloneBuffer) member of 'ClonedMessageData'". abort()ing as a result.	87	9.25 %
3 IPDL error: "Error deserializing 'data' (SerializedStructuredCloneBuffer) member of 'SerializedStructuredCloneReadInfo'". abort()ing as a result.	30	3.19 %

and for versions:

Version	#	Percentage
78.6.0esr	681	72.37 %
92.0	87	9.25 %
78.14.0esr	55	5.84 %
92.0.1	22	2.34 %
78.14.0	11	1.17 %
78.13.0esr	10	1.06 %
92.1.1	10	1.06 %

So the "Sunday ditch" is probably explained by ESR and with newer versions there seem to be less problems. For the rest, comment 3 still applies.

Comment 5

[BugBot [:suhaib / :marco/ :calixte]]

Since the crash volume is low (less than 15 per week), the severity is downgraded to S3. Feel free to change it back if you think the bug is still critical.
