I'm not sure how we arrived at these numbers, but for a RHEL5 system
which regularly runs 12k jobs, we have in /etc/sysctl.conf:

# we need more file descriptors due to Condor's port usage
fs.file-max = 1639200


And in /etc/security/limits.conf

# we need a lot of file descriptors for Condor work
*                soft    nofile          150000
*                hard    nofile          160000
