I know this is an old post, but rather than starting a new post thought I would add to it.
Anyway this problem has never completely gone away although it did appear to happen less and less. Unfortunately I wasn't very got at running the output from top to a text file to catch what was happening during a crash so failed to catch it and then learn to live with the problem. Now though the crashes are occurring more often and the other day I had the top output directed to a text file. The file is rather huge (over 3,000 lines), but the last few inputs are shown below.
Unfortunately I can't make a lot of sense from it or see what the problem is. Strangely enough the system crashed AGAIN today, but unlike other times I didn't even have time to open a program - as the desktop was loaded the fan revved up and the system became unresponsive. Any ideas anyone?
