n900 really laggy and unresponsive after running for 2 days.
 

Hey, I seem to have a problem with my n900.
Once I boot up the phone, the phone works extremely fast and everything. Its quite satisfactory.
But later on, after It being on for 2 days at a stretch, the phone gets extremely laggy and unresponsive. Everything is really slow and takes forever.
I couldnt even pick up a phone call when I was on the app manager, browsing.
Once I reboot the phone, its back to awesomeness.(for 2 days)
Any Idea?
Does anyone have the same problem?

Most likely some process is allocating memory all the time without letting go of it. This forces the kernel to put other processes in the swap to make room for the running ones.

In your XTerminal, run the command top and press m to sort by memory usage and check for processes that use a lot of memory. It's also good to look for processes that use a lot of CPU.

oh!
mem : 237676k used, 7312 free, 0k shrd, 1468k buff, 41544k c.

cpue :2.7%usr 1.5% sys 0.1% nice (changes from 96 84 n 69 %) idle 5.1% io 0.0

and usr/sbin/browserd is highest with 7.7 %.
what application is that?
im not running ANYTHING in the background.
what do I do to fix this?

Re: n900 really laggy and unresponsive after running for 2 days.
 

Is your device as unresponsive now as you described it in your initial post?

browserd is a daemon process that waits for you to start the browser. By using a daemon like this, start up times are kept to a minimum.

oh okay..
any idea on how to speed things up?
btw, ive installed the kernel for overclocking..but i havent overclocked.its still 250 to 600 now.
it lasts longer on the stability side, but battery wise not overclocking sucks.
and when i overclock it gets unresponsive in a day n a half.
n e idea on how to fix this?
i really dont want to reboot my phone every 2 3 days :(

You can leave the mass memory intact first, and see if any improvement happened. This will erase installed apps and settings, nothing more. (but of course it is good idea to take a backup if you have something important on the phone)

Re: n900 really laggy and unresponsive after running for 2 days.
 

oh no man..i really dont want to flash my phone..that would be my LAST option.
btw on conky, my Memory ("Mem:" rite below cpu usage on the right) is constantly high..its red n its almost full..could that be my culprit?
could buying a class six memory card and using it as ram fix things?

Re: n900 really laggy and unresponsive after running for 2 days.
 

It's a known issue last I checked, it's brought on by desktop widgets or Python or whatnot. Flashing doesn't help. It slows down just under 48 hours.

I reboot every day.

Re: n900 really laggy and unresponsive after running for 2 days.
 

hmmm i do have tonnes of widgets..but none of em use d internet or n e thing.
except rss feed..shud i remove em :(?

Re: n900 really laggy and unresponsive after running for 2 days.
 

It would slow down anyway, just a little slower. Still, most reports say that under 48 hours it becomes slow. Best way to check is CPU usage when unlocking, as the hildon whatchamacallit is getting worse. I think it's memory fragmentation.

Point is, wither live with a crippled device or schedule 4AM reboots. I chose b).

Get Alarmed and schedule reboots. What's the loss?

Re: n900 really laggy and unresponsive after running for 2 days.
 

I've heard RSS feeds can have an adverse effect on performance after they've been running for some time.

You could try removing the feeds, see how things go after that. Also try disabling any unnecessary repositories in app manager.

Re: n900 really laggy and unresponsive after running for 2 days.
 

Repositories? Where did you hear that?

Re: n900 really laggy and unresponsive after running for 2 days.
 

"Application Catalogues" as Nokia prefers to call them.
Having them all active can be a bit of a resource hog. And they can slow things down, especially when web browsing, because App Manager will be looking for updates.

watchamacallit = slide to unlock function?
btw i really dont want to reboot everyday.takes away a ton o battery.
btw, there will be days where the phone will have to run without recharging for two days in a row. then what?im screwed?

Re: n900 really laggy and unresponsive after running for 2 days.
 

ive only got one feed.thats from www.nokian900applications.com

and yeah will disable them iff removing rss doesnt do the trick.

Re: n900 really laggy and unresponsive after running for 2 days.
 

Rebooting doesn't take a ton of battery. What rebooting does is re-evaluate battery, which is more pessimistic then before, thus the apparent change in battery level.

If it would really take that much, rebooting again would leave you with even less. it doesn't do that on subsequent reboots. I don't expect a reboot to take anything over about one percent.

You lose more battery by having a slow system, as the system stays up and at peak frequency more.

Or, schedule reboots before plugging in. But there is no doubt in my mind that you interpreted the battery percentage (which is a guess) instead of voltage. If you want to test this yourself, reboot repeatedly and you'll see it drains nowhere near a significant amount, compared to, say, gaming.

Oh, and, removing RSS feeds and repos will not help significantly with memory fragmentation.

Ndi which program do you use to schedule reboots? Cheers

Re: n900 really laggy and unresponsive after running for 2 days.
 

This is a known issue from the start!
There is a bug filed for hildon-home (clickable stuff on your desktop like links contacts widgets...) becoming unresponsive after 48 or 96hours.
https://bugs.maemo.org/show_bug.cgi?id=8723

And several threads are talking about issues too.

Please make use of

A general help is not to use python based widgets on your desktop and read the related threads on tmo to programs you install and search for bugs at https://bugs.maemo.org

Stuck or unresponsive bits can be restarted by hand and do not need a restart. As root do
wait a second between the commands.
Example for home

Alarmed is a nice app that allows alarms and events in place of alarms, like command lines, switch profiles, go offline, etc. Pretty good, save for a highish startup time.

Re: n900 really laggy and unresponsive after running for 2 days.
 

Also there's fcron, if you don't mind playing with the terminal (there's no real GUI). I find that it has a slightly lower resource hit compared to Alarmed - but that could just be me.

Incidentally, I have a nice script running every day at 5.30am that gives out a warning (Your sistem will autorestart in 60 seconds, please save your data) before auto-restarting.

A shame I don't know how to make it an user input capable option (abort? restart if there is no user input?).

what are you talking about. My device are almoste never slow even after three weeks without reboot. Take care of your device and it will take care of you ;)
