OK so recently I have been suffering the infamous hildon-home memory leak.
After 2 days or so hildon-home starts to pop up and use 50% of resources every minute or so getting worse until you reboot, reinstall hildon-home or killall hildon-home.
Yes, I have read all the threads on here and they all end in mystery as to what the cause was, people reflash all is happy.

Out of interest (or for testing purposes) I have slowly been un-installing applications to find the bug.
Finding the bug the hard way is not working so far after uninstalling seemingly half of my applications in HAM.

Is it possible I am fighting a losing game and actually I could un-install everything and still need to reflash?

This is my stable device and I fairly strictly, install applications from extras only. Or if they have been tested for a few months on my testing device and there important, some from testing etc.

My testing device hasn't got this issue and it has some very unstable devel applications on it.
Also installed are all applications that's currently on my stable device too.
This is why I come to ask the above question.

Here's my "maemo-list-user-packages" output.
I have noticed some of these have been uninstalled but still show in the list they have been highlighted.

Do we think there is an application somewhere causing this for some to be affected and others not?

Will the solution ever be found and how?

There is a possibly it's an application long un-installed that's broken something, Will what it has damaged be reinstallable?

I have install --reinstall"ed"
Code:
hildon-home
hildon-desktop
hildon-input-method
hildon-control-panel
hildon-status-menu
Answers, solutions, theories and comments all welcome.

yes there is always a problem with hildon home ,Reboot ,most of the time is the only solution .It gets worse by the time ,so eventually you need to reflash your device .Cssu doesnt offer any help either .There should be something done about it . Thanks sixwheeled for bringing this up .

Hmm. Not that it helps much, but I haven't yet seen this issue on my N900s. One point of interest, though -- browsing through the threads, it looks like everyone thinks widgets are the cause (although nobody seems to have pinned down a particular offending widget). I actually don't run any widgets, which may be why I haven't hit the problem yet.

Is there a difference in the widgets running on your test machine and your stable machine?

No, the first thing I did after reading all the threads on here was remove all the "not pinned down" application suggestions including all widgets.

I have even apt-get remove the whole default rss app.

I have two widgets on my test device but none on my stable.
Also as I say the applications on my stable are the same as on my testing device now.

This is why I am asking the questions as nobody has really found an answer as to what causes it.

I would hate for a bug in a "stable" extras applcation not to be found causing this misery to many not in the know.
My thoery behind it being an applcation is a non-TMO friend has the same problem but not to the same extent.

He only uses the extras catalogue and has never ever used any other repos or CSSU.

Thanks for your suggestions, I thought I was going to be talking to myself for a while...

maybe you should try to trace memory allocations, though I simply don't know if it is possible on the device itself

3 desktop windows with 11 widgets on plus around 80 apps icons in app menu.When things are up and running in the background ,xorg shows up with 16 to 17 % of cpu usage .Hildon home also uses upto 11 % to 22 % of the cpu but only sometimes unlike that of xorg and also there is pulse audio,one of another culprit. I was really considering to do a Reflash today but since i have taken a lot of notes with penpen application ,kept me reluctant to do sucha thing . I wish it could be like any frigging fast device.Atleast there should have been some improvements after cssu .Actually without cssu ,N900 runs faster but looks a bit boring yeah . I hope some one blends something into hildon home .I read somewhere though that Xorg is the main culprit but on the other hand ,it is most necessary thing to keep the N900 up and running . Adios

Edit : between my N900 runs great .No problem what so ever ,its just that sometimes it gets so slow and kinda frustrating one . Sixwheeled problem is pretty much serious though .

Hey six wheeler,

is it like the process goes crazy and takes lot of cpu? And you do not recognize it, everything works normally, but you notice it by battery drain? Killing the process will get it started again and sort it out until next time happening?

If so gimme some more info, maybe I have a workaround for you. As on my device I experience that with hildon-desktop and made myself a solution (I have desktop-cmd-exec under suspicion).

Yes fairly similar.
It happens after a few days or so of light browsing with opera, heavy media player use and fairly heavy phone use. This is my normal usage pattern for the last 2 years or more.

This bug has happened on occasion in the past but it has more recently gone from happening maybe every month or more to 1-2 days.

It seems to be related to usage as if I reboot on a Friday the bug will not appear until Tuesday-Wednesday. If I reboot on a Monday it will be normally reappear by Wednesday.
I generally use the media player and phone applications a lot less of a weekend.

hildon-home starts popping up in top with about 50% CPU every minute or so. If you leave it for another day or so, eventually you notice heavy battery drain and hildon-home not responding messages under heavy load. At this point hildon-home is using 99% for long periods of time.

Although I am interested in your workaround my aim is to populate enough information to find the problem and get it fixed.

Here is my workaround. I hope it helps you to sort it out. Keep me/us informed.


I am still looking for a solution/workaround to detect "hanging" of hildon-home, not reacting on touches, and let me missing all notifications.
I can not detect and have no idea, when this happens. Any suggestions?
