Hi Cole,

thanks for the reply. In the mean time, we figured it out! Turns out
that we have a fixed setting of RESERVED_MEMORY of 8GB which was more
than the whole VM. So no memory was left at all for HTCondor to use.

Increased the memory of the VM, now it is happy. This one took a bit of 
sleuthing.

Cheers,

Dennis
