this does not sounds right.
engine and SPM should not communicate at 98% traffic for 2 hours.
SPM should be one of the nodes in the DC.
engine isn't acting as a node (even if deployed on one by chance of 
all-in-one or hosted engine).

are you creating the VMs from template thinly provisioned or clone?
