This is almost certainly a mismatch between the kernel version and a 
monitoring tool that is trying to inspect kernel state (specifically, 
retrieve process lists).  If your buildworld/installworld doesn't match 
your kernel version, then you need to rebuild and make sure everything is 
in sync.  If it does, it's probably a third-party package that is out of 
sync and needs updating.
