[philipp]

• shutdownhang signatures are not properly generating since yesterday and all those crashes end up under the signature [@shutdownhang | mozilla::`anonymous namespace::RunWatchdog]
  • https://bugzilla.mozilla.org/show_bug.cgi?id=1299769
  • socorro devs are aware of it and will regenerate the proper signatures for affected crash reports once the issue is fixed (hopefully today)
• async shutdown timeout crashes got more meaningful signatures and the underlying issues will be easier to differentiate with bug 1035144: http://bit.ly/2ctb3Ss
