Hello,

I also noticed this problem, and am determined to find the real solution.

I've had my n900 running for more than 5 days now, and the slowdown started, as expected. Looking at top revealed nothing, no apparent excess memory usage, or cpu load.

My first suspect was the browser daemon, so I restarted it with the following command:

/etc/init.d/tablet-browser-daemon.init restart

Of course this needs root.

After a little while this seems to have helped, the interface seems to be usable again, switching windows is snappy, and a lot less GUI lag than before the command. I'm posting this from the device.

I'm not saying this is the solution, but it might help others. I'll try to keep my device running for as long as possible, and will try to diagnose this if it slows down again. I'm far from an expert, but I know my way around Linux a bit to try this I think.

Anyway I'll post again if I find something new. I hope that this is solvable with enoguh effort, I'd like my phone to have as good uptime as my servers without problems.

Tamas
