What does this mean? I don't see any bad sectors on my four drives in mirror

That is about the swap space. A reboot will fix it.

Rebooting FreeNAS takes so much time though... I always get this error a couple of times and I have to restart it 5-10 times https://puu.sh/AfSeg/13801d0e1f.jpg

What is da3pi and da2pi? These are the names of my drives https://puu.sh/AfSeZ/21afedfc8b.jpg

What is da3pi and da2pi

From the graphic you posted, the names of your disk drives are da0, da1, da2, and da3. The p1 (not pi) is the partition that is used by FreeNAS for swap space. There is another partition, p2 which is where your ZFS data is stored. The drive (or drives) that are dropping out of the gmirror must be going offline for some reason. The ZFS system will automatically restore the mirror without even telling you if a drive is momentarily unavailable and comes back. The gmirror system isn't that smart. It will stay degraded until you fix it and the easy way to fix it is to reboot.
This is something that should only happen on rare occasions and you should know why.
If it is happening frequently and you don't know why, you should investigate because you are having some hardware problem that is making the drive unavailable to the system, which breaks the mirror, and then you get notified. If the drive is available and working when you check it, that means it is an intermittent fault. You might try replacing the data cable between the drive and the interface. Some people have had bad SATA cables cause issues.
It might be helpful if you gave a full rundown on the hardware you are using for this system.

I rebooted it, is there a command to check if it's still degraded?
