What I've done in the past is to have the first build run of all the massive
ports to be built, with a high -J, tmpfs=all and every port in the list
configured in poudriere.conf to not build these massive ports simultaneously. 

Then have another build run for all the other ports, which completes 
relatively quickly because the prerequisites for many things are 
already available.

This at the time resulted in a greater chance of all ports being built.
I think the total time (massive-ports-build+regular-build) may be less
but I'd have to check.

It seems to me that some ports fight each other when J =>2 and even this
320GB 20 CPU system will run out of resources (typically swap) if the build 
runs with the complete portsbuild list in one go. The above build never hit 
swap.
