Apparently, the disk load is so high on the processing machine that
condor is having problems communicating, resulting in submit failure.
When jobs are submitted to be run on the collector machine with the
same 100% disk IO, the job submission never fails, that is probably
because the OS and condor logs/etc files are on a dedicated SSD disk,
instead of on the RAID5 which is being 100% utilized. Not sure how
much it matters that the submission machine is the collector machine
and that the required machine is the collector for the case where no
jobs fail to submit.
