You don't get it if this is an admin user system. To get a core (on machines
other than Solaris were you can enable global core dump creation with

Once you have the stack trace please submit a P1 or P2 bug to Issuezilla
with the stack trace output. Please provide other information (like "qstat
-f", or "qstat -r" as well).
