Very strange TOP abort error

Hello, i have doing some tests with the latest image from
http://www.angstrom-distribution.org/demo/beagleboard/
and sometimes the top command fails like this, i also have noted the
top sometimes is very heavy on processor side...

Anyone have some idea???

Thanks in advance

Nuno
