That can happen if the process is in uninterruptible sleep (i.e. waiting
for IO to complete). If this is the case, ps and top should reveal the
process' status as 'D'.
The only time I've observed a process in this state is when experiencing
hardware problems, e.g., a process blocks in state D while tyring to read
from under /proc/bus/usb after the kernel's USB subsystem is hosed by my
evil MP3 player. So if your processes are in this state, try finding out
what file descriptor they are trying to read from (with strace -p $pid)
and then looking up the fd in the list of open files (lsof -p $pid).
Of course, it might be something totally different. ;)
