The problem here is that your job is run as a child of the condor 
daemons, which aren't PAM enabled, so the condor daemons don't read 
/etc/security/limits.conf.  A quick hack is to launch the condor_master 
as a child of a process which is PAM enabled, like the "su" program.  
So, in your startup script, instead just launching the condor_master, 
you can run

/bin/su root -c /path/to/condor_master

As init starts the master as root, the su is essentially a no-op, except 
that it reads the /etc/security.limits file.
