No, you can have much more than that. I don't know if there's any limit, but if there is, it's very much higher. I use a 512 MB swap partition. > I tried to seperate it into 2 partitions of 256 megs but then I had > trouble activating both swap patitions. The system would just mount > one. In general, it's a bad idea to have two swap partitions on one drive, since you're likely to have more positioning during swap. If this is what you've done, and they're physically contiguous, you should merge them. You'll need to boot in single-user mode to do this. On the other hand, two swap partitions should work. What does your /etc/fstab look like? You should have entries for both of them. What happens when you issue a swapon command for the other partition? What does 'pstat -s' say?

The amount of swap that FreeBSD requires depends on the application. It may be none at all, or it may be much more. I once inadvertently did a 'make world' on a machine without swap, and it completed normally. Greg -- When replying to this message, please copy the original recipients.
