You are running into the limit on the number of processes an individual user can
have open.  I have seen this before, all users signing on with the same name,
and typically with applications ported from a non Unix/Xenix environment.

Why not write the program so any user can log in under their own name - or
assigned name.  THis is in the spirit of the OS.   If you have to have
permission associated with the users make the program set used id so the user
runs with the effecive id of the program.  

You will probably see more problems in the future if they ever want to run
some other applications.  You can adjust the parameter for maxprocs using the
configure option, but you still ought to have the users have individual ids.
