Well that error is not a basic one.. which ps are you running (you can
find out by typing which ps). Something is locking your access to the
kernels memory so something has changed on the system from a default
install. I guess I need a lot more questions answered:

Type of system (x86_64, i386)
Type of hardware
The output of the following commands

df -a
ls -l /proc/
