It depends a lot on your workload I'd say.
for me its pretty stable on a amd64 7-STABLE box that just does a little
light mail and web and package building.
for others not so much.
info on my system below if anyones interested.

¿So no chances of ZFS stable on FBSD7? I was actually considering debian over freebsd on a dual AMD64, but if there are no settings that will make it stable... Nevertheless I'd be willing to help debugging ZFS on that machine (Dell T105) as soon as I receive it in a couple of weeks, as I'm in no rush to getting it into production (just tell me what to do ;) ).

Asunto: Re: ZFS deadlock
Depending on your work load you are just buying more time, so
"reasonable" is a matter of perspective. :( I didn't see if you said
you are on 32bit or 64bit? Keep in mind the kmem max is 1.5-2G on amd64
regardless of how much memory you have. If 512M arcsize crashes too soon
for your tastes you can always lower it down to 256M, or 128M, etc.
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.
Spike
