1109097 - [e10s] Hang on shutdown with "Couldn't load symbols for" for various modules

Status: RESOLVED INCOMPLETE

(Core :: IPC, defect)

Description

[Henrik Skupin [:whimboo][⌚️UTC+1]]

Mozilla/5.0 (X11; Linux x86_64; rv:37.0) Gecko/20100101 Firefox/37.0 ID:20141209030205 CSet: f1f48ccb2d4e

I can see a hangs on shutdown of Firefox with e10s enabled. After a while the build gets killed with via the 'mozilla::::RunWatchdog' (bp-55182e21-06e3-4b01-bfa0-fc62b2141209).

I haven't found consistent reproduction steps yet. If this is not a dupe, let me know and I can figure something out.

Here the command line output:

Henrik: this does not seem to be a duplicate bug. Have you found any STR yet?

I haven't used e10s mode for a while, so I wasn't able to even reproduce it. Lets close as incomplete for now. I will reopen if it starts to happen again once I switched over to e10s mode.
