Hi all,
in the recent weeks I am experiencing serious stability issues on two of my machines running KDE 3. I know KDE 3 is not Trinity and whatever the causes are they might be fixed in Trinity, but nevertheless I believe that the debugging techniques are identical for KDE and Trinity. That's why I'm asking for help here.
Machine 1 On first of my machines I am experiencing random desktop freezes around two times a day (this started around 2 weeks ago). When this happens the current application becomes irresponsive and I am unable to switch to different application by using Alt-tab or by clicking on the task bar. I am able to kill the graphical environment using Ctrl-Alt-Backspace or go to text console (Ctrl-Alt-F1) to kill tasks. I was unable to find any program that, when killed, would unfreeze the desktop. The only puzzling thing is that killing Firefox seems to make it a zombie process.
Machine 2 That machine experiences random problems when loading the desktop after login. The problem manifests itself with an error message from KDE panel saying that "'/home/USER/.local/share/applications/foo.desktop' service is broken" (where foo is an application like Skype, Firefox, etc.) and then the KDE panel becomes irresponsive. Again, this is random and sometimes the desktop loads correctly.
In both cases I have no idea how to debug the encountered problems. Are there any logs that could point me the source of the problems? Are there any diagnostics that I could run? Any ideas appreciated as I fell clueless.

Hi!
You checked your hardware and it's OK?
Nik
You checked your hardware and it's OK?
No, I have not checked. In the case of first machine I'm nearly 100% certain that this is not the fault of the hardware. I'm not so sure about the second machine - it's an old computer and it has experienced minor hardware problems. Not sure what exactly I should check and how should I do it. I was thinking about running hard-disk checks - if anyone can recommend good program for doing that it would be great.
Still, are there any KDE logs that could be helpful in searching for the cause?

It doesn't sound like hard disk problems to me, but it's good to keep an eye on the condition of your drives. With smartctl (package smartmontools) you can see all the S.M.A.R.T. info, error logs, etc. and run the drive's selftests. Use badblocks to do a surface scan of drives or partitions.

Hi,
To test a computer's reliability, a good test is to run memtest86+ on it. You can download the iso and burn it to a disc, or it often comes as one of the options on the grub menu of many livecds. If after 10-15 minutes you see no red on your screen, the you can be sure that the path between the cpu-chipset-ram is good to go.
Remember also that older TDE releases (such as 3.5.13.2) and old KDE3 is not thread-safe. This means that on multi-cores computers, troubles may happen where an app is waiting on another and it creates lock-ups. My Asus EEE X101CH is a special case where I had many thread lock issues. Most of these has been solved on newer TDE releases (such as the soon-to-be-released R14.01).
Hope it helps! -Alexandre

Hi Janek, hard to say, it could be many things. Did you do any sw update to the machine recently (for example kernel)? The machine 1 issue sounds like kicker is frozen. You can try going to console and run ps aux |grep kicker and see what happen. You could also try to kill kicker and launch it again. Same goes for kdesktop
For machine 2 I would suggest trying to create a new account and see if the problem happens there as well. If not, maybe some files in your home folder got corrupted/inconsistent.
Also ~/.xsession-error may give a clue.
