I have 8 gigs of memory in this system, and I decided go to the ZFS route, and am now getting kernel panics about kmem exhaustion. I know there are some tweaks I can do to help alleviate these, but I want to address all my memory before I increase the kernel memory. I don't need the ports to be 64-bit, but they SHOULD run just fine without recompiling, yes? --Andy On Feb 23, 2009, at 12:05 PM, Roland Smith wrote: > On Mon, Feb 23, 2009 at 11:30:10AM -0800, Andrew Moran wrote: >> >> I installed the i386 distro on my Core 2 Duo instead of AMD64 and now >> I want to switch to using AMD64. > > First of all, your Core2 Duo should work just fine with i386.
