Solaris 10, u3, zfs 3 kernel 118833-36.
Running into a weird problem where I attach a mirror to a large, existing filesytem. The attach occurs and then the system starts swallowing all the available memory and the system performance chokes, while the filesystems sync. In some cases all memory goes away and the system becomes unresponsive. If the system is left to itself for the time it should take to sync the disks, the sync doesn't occur. It can ping but won't allow logins, even from console. So I break the system (a v490) to PROM, boot -s and when the system comes up the mirror starts resilvering (from 0%), available memory goes to 230mb (from 32GB) at the rate of about 1GB/15 secs and then hops up to 4GB when it hits bottom. I let the system alone and allow the sync to complete, all the while having really slow console access. zpool status will show that the pool is in a good state, then I allow the system to come up to level 3 by exiting console, the sync of the mirror restarts at level 3, zpool status shows the mirror resilvering and the system begins the memory swallowing and goes into an unusable state, without even console access.
