[Bug 1656065] Re: Firefox and plugin-container (Chrome_ChildThr): segfault at 0 ip, sp error 6 in plugin-container/libxul.so

[daniel CURTIS]

Hello Robie.

Unfortunately, this problem appeared again. Today, I have had Firefox
enabled with just two tabs: YouTube and Google Translate. Suddenly,
system start to slow down, disk diode was... red all the time, mouse
cursor moved slowly etc. After a couple of minutes, I managed to start
terminal and used '$ killall firefox' command, which helped -- system
started to work faster again, clicking e.g. on a file, opened Mousepad
almost immediately, in milliseconds etc.

Log files (such as '/var/log/syslog' or '/var/log/kern.log') contains:

✓ Sep  4 13:46:00 holycross kernel: [10194.439105] Chrome_~dThread[3599]: segfault at 0 ip b03f6b24 sp afaa1040 error 6 in libxul.so[afb73000+570f000]
✓ Sep  4 13:46:00 holycross kernel: [10195.084439] Chrome_~dThread[4040]: segfault at 0 ip b042fb24 sp afada040 error 6 in libxul.so[afbac000+570f000] 

As we can see, there is a problem in 'libxul.so'. (See bug title.)
Firefox version: 55.0.2 (32-bit), e10s enabled (4. processes; changed
from 2. after update), four addons, no Flash. RAM memory checked with
memtest64 - no problems.

I will keep an eye on this, because of a couple of months without
problem. Maybe it was just an accident?

Thanks, best regards.
