[Desktop-packages] [Bug 987060] Re: massive memory leak in unity-panel-service and hud-service when invoking the hud on Firefox profiles with large amounts of bookmarks LTS 12.04 14.04
The document is a compressed PDF of about 4 megabytes, it's mostly text but with some images. It's about 240 pages long, but you're right it has a detailed index. I can't share it here though unfortunately, it's a commercial ebook. (Drop me an email at k...@kzar.co.uk , I'll share it with you for purposes of reproducing this issue if you promise not to share it and delete it afterwards.) Steps to reproduce?

The problem for me seemed to have been caused by having a single very large PDF on my Desktop. Even after stopping hud-service from executing I noticed that nautilus was consistently using 15% of one CPU core, but as soon as I moved that PDF somewhere else the problem went away. I've now allowed hud-service to run again, rebooted, and things appear to be working nicely again. Observations: - Why is generating the preview icon for a large PDF so costly? Surely only the first page should be read and used for that purpose? - Surely these preview icons should be cached? - I think even if generating the preview icon is expected to be costly, there is a bug here as there is definitely a memory leak + the CPU usage stayed consistently high for hours. Surely the process should finish and then the CPU usage should drop away again? -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/987060 Title: massive memory leak in unity-panel-service and hud-service when invoking the hud on Firefox profiles with large amounts of bookmarks LTS 12.04 14.04 Status in Unity HUD: Confirmed Status in Application Menu Indicator: Confirmed Status in Unity: Won't Fix Status in firefox package in Ubuntu: Incomplete Status in hud package in Ubuntu: Confirmed Status in unity package in Ubuntu: Invalid Bug description: unity-panel-service and hud-service quickly racks up memory and CPU usage until I kill it when invoking the HUD on Firefox.

I'm also finding that the hud-service process has started leaking memory + CPU recently. It was never a problem for me before. As I speak it's using 100% of one CPU core and 5.5gig of RAM! I'm finding it like that each morning and having to reboot before I start work for the day. - Ubuntu 15.04 - Linux stoa 3.19.0-30-generic #34-Ubuntu SMP Fri Oct 2 22:08:41 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux - Thinkpad T450 i7 with 16gigs of ram I don't really use Firefox, although I occasionally start it to test things. I have few/no bookmarks in Firefox. If someone can explain how I can obtain the debug symbols for hud- service I'll have a go at running it under Valgrind. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/987060 Title: massive memory leak in unity-panel-service and hud-service when invoking the hud on Firefox profiles with large amounts of bookmarks LTS 12.04 14.04 Status in Unity HUD: Confirmed Status in Application Menu Indicator: Confirmed Status in Unity: Won't Fix Status in firefox package in Ubuntu: Incomplete Status in hud package in Ubuntu: Confirmed Status in unity package in Ubuntu: Invalid Bug description: unity-panel-service and hud-service quickly racks up memory and CPU usage until I kill it when invoking the HUD on Firefox.
