Okay, Thanks!

I think it's because there's no space left at tmp to create the mapping file. But let's produce a better diagnose for that - Bug 1519355

Comment 3

[Jared Wein [:jaws] (please needinfo? me)]

Martin do you think you will now be able to fix this with bug 1519355 fixed or should we mark 65 as wontfix, considering we're running out of time for uplifts for 65.

Comment 4

[Martin Stránský [:stransky] (ni? me) (PTO, back on Feb 17)]

It should be marked as wontfix, I don't see any new crashes with this signature. I'll investigate it if there's anything new.

Comment 5

[Neha Kochar [:neha]]

Martin, there are crash signatures from Feb 28 to Mar 3. Can you please look into this for the 67 soft freeze (Mar 11)?

Comment 6

[Martin Stránský [:stransky] (ni? me) (PTO, back on Feb 17)]

Unfortunately there's nothing new at the reports, I may need to put more debugging info/logging to the failure.

Let's handle it at Bug 1543687.
