My machine behaves well. One make buildworld ran without problems.
No I do a make -j 16 buildworld in a "while loop" to stress test
CAM and softupdates. I'm not running X for this test, to see the
messages on the console if something bad happens ;-)
I'll keep you informed. Here my system configuration for reference:
