Can anyone help me with this?  Thank you.

         PVM Bug Report   27 Sept 94
 * The exact version, patch level you're using 
    I'm using PVM version 3.3.4
  
 * The machine type(s) you're using, hardware and software
    I'm running Solaris 2.3 (SunOS 5.3) on a Sun SPARCstation
    10/514MP with 4 processors:
    SunOS sherlock.hgen.pitt.edu 5.3 Generic sun4m sparc
     
 * The machine architecture PVM chooses for you (e.g. ALPHA).
    SUNMP

 * A short description of the problem (what happens, when, etc.).
     When I run the master1 example program, it gives 
     the following error message when I ask to spawn
     too many slaves:
libpvm [t40006]: peer_conn() shmat to t40008: Too many open files

     Also, if I try to spawn a task on the SUNMP machine as a
     'slave' host from another 'master' host, it
     fails to spawn the task.

 * A record of what you did to make it happen.
