I disagree - anything that causes a panic is a stability problem. Panics =

persist AFTER the tunings (for i386 certainly, and there are unsolved=20
reports about it on amd64 also) and are present even when driving kmem=20
size to the maximum. The tunings *can not solve the problems* currently, =

they can only delay the time until they appear, which, by Murphy, often=20
means "sometime around midnight at Saturday". See also the possibility=20
of deadlocks in the ZIL, reported by some users.

I did, once to Pawel and once to the lists. Pawel couldn't help me and=20
nobody responded on the lists. Can you perform a MySQL read-write=20
benchmark on one of the 8-core machines with database on ZFS for about=20
an hour without pause? On a machine with 2 GB (or less) of RAM,=20
preferrably? I've seen problems on i386 but maybe they are also present=20
on amd64.
