Does this also happen when not in daemon mode?

Have you tried with smaller sizes of doublebuffering (for example
-z:db,100000). Db of million frames is quite a lot. It might be that
adding the second file causes the machines to run out of physical memory
and to start heavily swapping. This would explain the spike in cpu load.
