You can prevent this information being displayed to the user by changing the pf_tracelevel option in the global_profile.conf.
Use either the 'pmpolicy edit' command on the policy server, or Management Console for Unix to edit the global_profile.conf file.
From:
pf_tracelevel=1;
To:
pf_tracelevel=0;
This will result in no information being displayed to the user after they use the pmrun command.
