It looks like your machine has run out of shared memory.  One problem
with shared memory is that is is not reclaimed when the processes
using it terminate.  Let this go on long enough and no space will be
left.  There is usually a program called 'ipcs' that will show you
what shared memory is allocated and another called 'ipcrm' to remove
them.
