The box runs less than 20% load. Everything has been working perfectly until two days ago, now it can take 10 minutes to exit from vi. The following truss shows that the 3 line file that is sitting on the ZFS volume (/archives) took almost 15 minutes in fdsync.

/me have similar observations. With virtual no other activity on the box exiting from vi (:wq) sometimes takes 10-60 seconds. Trussing the process always shows vi is waiting in fdsync(). This happened on at least two different machines:
- Sun E3500 with ZFS on A5200 disks (snv_37, almost all of the time large
  delay (10-60 secs.) when exiting from vi)
- Solaris/amd64 with ZFS on SATA disks (snv_39, but only few delays, usually
  not longer than 10 secs.)
