>Description:
I am running buildworld and buildkernel with -j9 option to make and I am watching the top while it is building. Quite often the top screen gets corrupted with "kvm_open: cannot open /proc/42997/mem" or similar. I am running the top as root so it should not be a permission problem. The top says "Top version 3.5beta12".
