Hi,
After reflection, i guess you didn't want the headers line of ps command. 
And i think use of multiple renamed Headers in one -o option doesn't work 
as:
[senglont at artemis1 lsf-ompi]$ ps -o ppid=X,comm=Y -u senglont
X,comm=Y
    4080
    4082
    4162
    4164
    4165
   21488
   21491
   21492
    4083

Cause all characters after the first '=' would  be taken as a string, so i 
think you should use one -o option for each renamed Header as:

[senglont at artemis1 lsf-ompi]$ ps -o pid= -o ppid= -o comm= -u senglont
 4082  4080 sshd
 4083  4082 bash
 4164  4162 sshd
 4165  4164 bash
21488  4165 man
21491 21488 sh
21492 21491 sh
21497 21492 less
23548  4083 ps

I'll modify and re-try.

I was testing further and there's still another problem, i guess it came 
from the ps command you changed.

[senglont at artemis1 lsf-ompi]$ ./padb -O rmgr=lsf -tx 1516

Here's the result of the break point after the call to slurp_cmd:

[senglont at artemis1 lsf-ompi]$ perl -d ./padb -O rmgr=lsf -tx 1516

In my version the ps command was:

my $cmd = "ssh $host ps -o pid,ppid,cmd -u $target_user ";
which display this on host 'artemis4':
