[GE users] SGE on Debian-64 interactive qrsh without limits

Hi all,

with our new Opteron cluster we try to use Debian. Before we used  
SuSE on the 32 bit machines. One issue I have are the missing hard-  
and soft-limits for interactive jobs. With batch jobs the limits I  
can check successfully with ulimit in the script. So I wonder,  
whether this is a Debian or SGE (configuration-)problem, and would  
like to get from SuSE-64 and Debian-32 users the statement, which  
behavior they see, as I have only SuSE-32 and Debian-64 accessible.  
(SuSE 9.3, SGE 6.0u7, Debian 3.1)

** On  SuSE 32-bit.

Note the missing "login -- reuti" on Debian.

(The command line "qrsh -l h_cpu=60 ulimit -aH" is working correctly.)

Thx - Reuti
