Re: System Slow Down Every 3 Days - Possible Memory Leak?
 

I don't have any python widgets on my desktop yet I still need to reboot every week or so as the lag becomes ridiculous.

There are still a few what I would consider fatal flaws with the N900 at this time, the forced reboots being one of them. My N810 is almost never rebooted. A family member's ipod touch never gets rebooted. But the N900 does. Which one doesn't belong? I don't think my 770 had to be rebooted but it's web browser would randomly die so it might as well have needed reboots.

you could try killing the process.....i've done that a few times but i'm not sure how much of a "restart" that is.

Re: System Slow Down Every 3 Days - Possible Memory Leak?
 

Try the following:

$ killall hildon-home

I have the same problem and it seems it is a problem of hildon desktop than the whole system (the menu button on top left remains fully responsive for me). However, restarting hildon will remove all your 3rd part widgets and you will have to put them back again :(

Re: System Slow Down Every 3 Days - Possible Memory Leak?
 

The "possible memory leak" described in the OP is the fragmentation of memory by python widgets. The symptom of that is an unresponsive desktop/task switcher. The hildon-home problem that seems to have surfaced with PR1.2 i still get but it's a bit less disruptive (eats battery and slows things down esp. when task switching) rather than completely freezing UI.

There are definitely some kinks to work out but, as i said, going back to an almost empty desktop really helped with the symptoms the OP describes.

Re: System Slow Down Every 3 Days - Possible Memory Leak?
 

I've tried pkill hildon-dektop as root and it seemed to do the trick. the widgets didnt disappear, and the system feels refreshed. ill see how long i can keep this going without rebooting.

Right now Im @ 3 days 21:15

Re: System Slow Down Every 3 Days - Possible Memory Leak?
 

IMHO the memory is getting fragmented a lot.
Here's the fragmentation info. There's hardly any segment above 64KB available after 2 days of runtime.

Normal: 1024*4kB 1636*8kB 394*16kB 12*32kB 1*64kB 0*128kB 0*256kB 0*512kB 0*1024kB 0*2048kB 0*4096kB = 23936kB

Here's how I got this info

echo m > /proc/sysrq-trigger
dmesg

Re: System Slow Down Every 3 Days - Possible Memory Leak?
 

I do not have Python widgets or Python installed. I am still experiencing this problem. In fact, I have been experiencing it long before PR1.2.

Re: System Slow Down Every 3 Days - Possible Memory Leak?
 

Try these steps too.

http://www.linuxinsight.com/proc_sys...op_caches.html

Writing to this will cause the kernel to drop clean caches, dentries and inodes from memory, causing that memory to become free.

To free pagecache:

* echo 1 > /proc/sys/vm/drop_caches

To free dentries and inodes:

* echo 2 > /proc/sys/vm/drop_caches

To free pagecache, dentries and inodes:

* echo 3 > /proc/sys/vm/drop_caches

As this is a non-destructive operation, and dirty objects are not freeable, the user should run "sync" first in order to make sure all cached objects are freed.

OMG



this was the reason why PR1.2 was delayed

i logged a bug about this a long time ago
https://bugs.maemo.org/show_bug.cgi?id=8723


thanks for not fixing it nokia.

i have no widgets running anymore and i have to do this every few days


sudo gainroot
killall hildon-desktop
killall hildon-home

Re: System Slow Down Every 3 Days - Possible Memory Leak?
 

continuously flush the cache:


#!/bin/bash
for ((i = 1; i < 1000000; i++)); do
echo 1 > /proc/sys/vm/drop_caches
sleep 1
done
