I have seen this too. Although I have never tested it, the solution
seems to use $ORACLE_HOME/rdbms/admin/utlprp.sql instead, see below for
the relevant snippet from the header of that file (BTW ultrp is
implemented as a simple call to utlprp with parameter 0)

Rem      The degree of parallelism for recompilation can be controlled
Rem      providing a parameter to this script. If this parameter is 0 or
Rem      NULL, UTL_RECOMP will automatically determine the appropriate
Rem      level of parallelism based on Oracle parameters cpu_count and
Rem      parallel_threads_per_cpu. If the parameter is 1, sequential
Rem      recompilation is used. Please see the documentation for package
Rem      UTL_RECOMP for more details.

Subject: Running utlrp creates too many Pnnn processes

We recently created some databases on Solaris 10 machines and I'm having
a problem running $ORACLE_HOME/rdbms/admin/utlrp.sql.

To the best of my knowledge, I downloaded the correct files for the
installation on a SPARC, 64-bit machine.  The installation completed
successfully and patching to also completed successfully.
Database creation completed successfully, too.

My problem, however, is that when I run utlrp, Pnnn processes start up
uncontrollably.  If I have the processes parameter set to 100, so many
Pnnn processes start up that it reaches the maximum number of processes
allowed.  If I increase that value to 200, the same thing happens.  I
also tried increasing the sga_max_size and sga_target values, but that
also made no difference.

Has anyone ever seen this problem before?  I've searched Metalink, and
opened a Service Request with Oracle, but have not gotten any
information back, yet.

Any thoughts/suggestions are welcome.
