Just like it says, you are running out of proc table slots (a proc
table slot is required for each process in the system).  There are two
possibilities here:  1) you may be running a kernel that isn't
configured for enough users; you should increase the "maxusers"
parameter in your configuration file.  2) you have a process which is
forking uncontrollably.  In this case, all you have to do is track it
down and stop it (preferably at the source; usually a student either
playing with multi-processing or trying to crash the system).  The very
last proc table slot is reserved for root;  log in as root and run ps
to find the culprit.
