Check the output of the following commands on the machine where you see
this problem:

condor_config_val -v NUM_CPUS

condor_config_val DETECTED_CORES

condor_config_val -v COUNT_HYPERTHREAD_CPUS

I'm guessing that your LOCK directory
/tmp/condor-lock.ddgrid0.745993478763015 has been deleted. Running
condor_init should recreate it. However, I would recommend reconfiguring
LOCK to be somewhere else--not in /tmp--so it doesn't get accidentally
deleted again in the future.
