I suppose you could do this by either changing GLOBAL_MAX_PROCESSES in 
/usr/lib/condor/libexec/linux_kernel_tuning, or turning off "kernel 
tuning" altogether in /etc/condor/condor_config: ENABLE_KERNEL_TUNING = 
false. I prefer the latter, and set the required sysctl values in 
/etc/sysctl.d/ (as they are system-wide and shouldn't be trigged by the 
startup of any specific service).
Cheers,
Marco
