I am not sure what you are hitting but since swap is a shared
resource it is possible that you are running out because of
other activity. The rctl is a limit, not a reservation, so
if something else in another zone or the global zone uses up
swap, even for a short time, while the one specific zone needs
it, then you could get an error.

Yes, that sounds normal since each zone is using something
different. I was referring to the 'size' column, not the 'used'
