1255844 - plugin-container crashes my computer due to memory leak

Status: RESOLVED INCOMPLETE

(Core Graveyard :: Plug-ins, defect)

Description

[Ronald J Kimball]

User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.10; rv:45.0) Gecko/20100101 Firefox/45.0
Build ID: 20160303134406

Steps to reproduce:

Used Firefox over a period of several days, visiting various websites, leaving Firefox running the whole time.


Actual results:

My computer crashed and rebooted, apparently due to a memory leak in plugin-container.

Upon rebooting, the Crash Reporter included the following information:

*** Panic Report ***
panic(cpu 3 caller 0xffffff8000d6aad5): "zalloc: zone map exhausted while allocating from zone kalloc.8192, likely due to memory leak in zone kalloc.128 (4175237120 total bytes, 32619019 elements allocated)"@/SourceCache/xnu/xnu-2782.50.1/osfmk/kern/zalloc.c:2521

0xffffff81df73bfb0 : 0xffffff8000e344c6 

BSD process name corresponding to current thread: plugin-container


Expected results:

Firefox should not crash my computer.

And now, your moment of Zen:

https://support.mozilla.org/en-US/kb/what-is-plugin-container
"Firefox runs plugins, like Adobe Flash, in a 'plugin-container' to prevent Firefox from crashing."

Comment 1

[Benjamin Smedberg]

Ronald, can you please copy your about:support information to this bug? I want to make sure that this is plugins and not e10s content processes (both of which run in plugin-container). If this is plugin-related, it could easily be a bug in the plugin (probably Flash) and not Firefox.

Also it may be valuable when you see this again to visit about:memory in the browser, save a memory report, and attach it to this bug.

Comment 3

[(No longer employed by Mozilla) Aaron Klotz]

Wow, so this looks like exhaustion of kernel memory. Hardware acceleration, perhaps?

Comment 4

[Ronald J Kimball]

Attachment: memory-report.json.gz

Firefox just started being unresponsive.  I have attached a memory report.

Comment 5

[Andrew McCreight [:mccr8]]

There are two ghost windows in that report, so that could cause some unresponsiveness. Otherwise, nothing in there looks too ridiculous at a glance, as it seems like you have a decent number of tabs. There's no content process report in there, which suggests this is not e10s content process related.

Comment 6

[Eric Rahm [:erahm]]

about:support also indicates this is non-e10s, so presumably it was an actual plugin.

Comment 7

[Eric Rahm [:erahm]]

Ronald can we get the list of plugins from about:plugins?

Comment 9

[Eric Rahm [:erahm]]

If possible we'd suggest disabling a few plugins at a time to see if you can pinpoint which plugin is causing this.

Comment 10

[z_mashine]

This behavior is also observed in a clean profile. So from the plug-ins/addons it does not depend.

Comment 11

[Benjamin Smedberg]

Unfortunately I don't think there are clear next steps for this bug, so I'm going to resolve it.
