425535 - Leaks after using Minefield for hours.

Status: RESOLVED INCOMPLETE

(Core :: General, defect)

Description

[Gary Kwong [:gkw] [:nth10sd] (NOT official MoCo now)]

Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10.5; en-US; rv:1.9b5pre) Gecko/2008032604 Minefield/3.0b5pre

STR:

- Run Minefield for hours (>6-12 hours++) opening and closing many tabs (normal usage) using leak gauge script.
- Sometimes I even hit 80+ tabs.
- Visit websites that make use of movie plugins e.g. flip4mac
- Sometimes I fire up Parallels in another directory to run a VM, occasionally causes Minefield to stall briefly, but not hang or crash, just shows spinning bob.
- Close Minefield.

NOTE: I hit this occasionally only when running and using the build for *hours*. Doesn't occur when merely running the sites below, even on a fresh profile.

We're really going to need better steps to reproduce in order to try to fix this. Any help with that would be hugely appreciated. Could you see if some combination of your actions, probably including the urls loaded in the log, could reproduce the leak?

The main difference is that this instance, there was still much tab opening and closing, but Firefox was only open for about just over an hour when I closed it. I recall watching the occasional YouTube video in this session.

(Hopefully I'll compile a debug trunk Firefox build to try and obtain more information)

Attachment: leak log

Alright, reproduced with a debug build from an hour ago. Attached is the output, the last few lines are listed below:

 => mAllocCount:          58509
 => mReallocCount:        10572
 => mFreeCount:           58202  --  LEAKED 307 !!!
 => mShareCount:          62780
 => mAdoptCount:           6549
 => mAdoptFreeCount:       6546  --  LEAKED 3 !!!

Program exited normally.

STR:
- Create a new profile, then go YouTube and create a number of tabs of YouTube videos (~5-6)
- Save and quit the profile.
- Run the profile again.
- As the tabs are loading, save profile and quit the application.
- Leaks shown.

(Fresh profile, no extensions)

The last log doesn't show us leaking any significant amount of stuff at all?

Comment 5

[Carsten Book [:Tomcat]]

might be the same as in Bug 419162

Comment 6

[Damon Sicore (:damons)]

Not blocking on this as it's likely related to other leak bugs.  We'll mark as wanted-next.

[Gary Kwong [:gkw] [:nth10sd] (NOT official MoCo now)]

I don't think I have more information on this one year on. Resolving incomplete.
