Attachment: Memory Report Preceding the Crash

This bug was filed from the Socorro interface and is 
report bp-cb2aad25-076a-48d5-8fd5-2ccdc2140331.
=============================================================

The Story...
I'd been getting crashes which were frequently preceded by black drawing on the UI. I looked into about:crashes which led me to bp-cb917cc6-e1a2-4cda-ad70-5aa762140325 and bug 805406.
Was instructed to save a memory report when things started going south.
I did so, but my next crash led me to bp-5cb8e782-9804-432b-acac-132df2140329 and bug 988619 (where I uploaded the memory report).

This most recent crash had no bug associated with it, so here we are.
Things got real hinky yesterday with freezing/unresponsiveness. When prompted to kill Flash I did and things surprisingly got normal.  Here is the hang report from then: hr-20140331-4fa83795-57d0-4080-8b25-f45639e8e8cf

It finally crashed today and I got a memory report 20-30 minutes prior.

I'm attaching my memory report, so don't judge my porn fetishes (kidding!).  I am a heavy tab user, however most of them are unloaded/unrestored.

P.S. I noticed no black drawing on the UI preceding this most recent crash.

Benjamin, we have a case here where a long-term community member has OOM issues that run into different signatures, and we have a memory report from (hopefully) not too long before the crash.

Who can look into that memory report to find out if there's a bad pattern? Is there something else that Caspy7 can try that gives us more info on any subsequent case?

Redirecting.

The memory report shows 77,996 event-counts and 7,974 observer-service references. The crash report shows a couple dozen extensions loaded. It's possible that one or more of them are causing a bunch of stuff to stay alive.

Nick has some good advice in 905131:

Hi Caspy7,

Part of it is just that you have quite a lot of windows and tabs and add-ons. But this is suspicious:

│    ├───87.97 MB (05.04%) -- top(none)/detached
│    │   ├──68.08 MB (03.90%) -- window(chrome://browser/content/browser.xul)
│    │   │  ├──49.84 MB (02.86%) ++ js-compartment([System Principal], about:blank)
│    │   │  └──18.24 MB (01.04%) ++ (3 tiny)
│    │   └──19.89 MB (01.14%) ++ (7 tiny)

As is this, which probably has the same root cause:

│  ├──23,122 (29.65%) -- top(none)/detached
│  │  ├──23,048 (29.55%) ── window(chrome://browser/content/browser.xul)/dom/event-listeners [31]
│  │  └──────74 (00.09%) ++ (5 tiny)

It looks like the whole tab has been leaked. And yes, there's a good chance it's one of your add-ons :(

Caspy7, if you are able to find out which add-on may play a role here, that would be very helpful, as we could try getting in contact with the add-on author or try other steps to get the problem solved.

Some firefox.exe stacks before it crashed. 64-bit Windows 7, 12 GB RAM, 2.6 GHz i5 quadcore CPU (25% in use by firefox.exe, hanging the entire process).

[Caspy7]

Clearing the needinfo as I am not seeing the consistent crashes I was (or crash reports) and I really don't know how to read / explore about:memory reports so I'm not sure how I can help at the moment.
