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. >> whereas looking at the size of tmpfs via 'df' will tell >> you how much total VM the machine has.

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