cpu-load

I have experienced 2-3 unexplained lockup over last 10 days.

Today, I had a random lockup (no mouse, keyboard response, 100% CPU). But, when I finally switched (Ctrl-Alt-F1) to command line (it took several minutes) it told me that thunderbird-bin had locked a CPU.

I ran this to resolve:

pidof thunderbird-bin
sudo kill ####

However, after saving other work, I tried restarting Thunderbird. It went to 90%+ CPU, and within 20 seconds it locked again.

Once I have more detail I will raise a bug (on Ubuntu Forums).

Does anyone have any other suggestions, advice?

UPDATE

Thunderbird 13.0.1 is quite stable in safe mode. Still working to resolve ..

I have seen in some version of Ubuntu that instead of making a huge change to update to the latest kernel, they take some of the good stuff out of it, for the sake of stability and put it on a previous version.

I read on Wikipedia that Windows 7 on a 64-bit PC needs twice as much RAM as on a 32-bit PC. I understand why is that: every number stored in memory takes 8 bytes rather than just 4. That, in simple terms, means that your amount of RAM is reduced to half when you use Windows 7 on a 64-bit computer… >>> More
