Is MAXUPRC broken in SunOS 4.0.3 ?

[Christine Hogan]

On our SS1 running SunOS 4.0.3 there is no limit on the number
of processes a user can run, despite MAXUPRC being defined to be
25 in our sys/param.h.  Has anyone else noticed this ?
One of our more malicious users overflowed the process table last
night, which shouldn't be able to happen.
Is this fixed in later releases (we may be upgrading soon) ?  Is
there a patch available to fix this ?  We do not have the sources. 

Thanks in advance.
