I tried for several weeks to get ZFS stable on a 64bit system with a 
1.5G kernel.  The best uptime I ever got was 72 hours, the worst was 2, 
the average about 24.  Interestingly, most of the hangs were at off 
hours, when the system was lightly loaded, had lots of free memory, etc. 
  That suggests to me a slow leak of some sort.

Anyway, ZFS is not ready for production.  Some people may get lucky, but 
  you can't count on it.
