Thanks, Memory is not a problem. I have plenty before and after (see bellow) the first time runing the benchmark. The vncserver crashed on the second run.
total used free shared buffers cached
Mem: 7995 1494 6501 0 31 991

I have the same problem on various machines (intel and AMD processors) all runing the same OS and software.
I don't have similar problems with other softwares
When running matlab without grapic mode (matlab -nodisplay) the problem vanished. However I don't have any graphics.
Any sugssition how to solve this problem?
