So up to 3 builders can be active at the same time.
You seem to have described only 1 builder's activity.

Was it the only active builder? If other builders were
active at the time you also need to check on what they
were doing. The ~2GB is the total across all activity,
including the (up to) 3 builders.

A command that would show the active builders would be:

# poudriere status -b

where:

     -b           Show details about what each builder for the matched builds
                  are doing.

I suggest reporting the "poudriere status -b" output
from a time frame with the ~2GB of swap space active.

Until then, there is insufficient information to have
a yes/no answer.
