I'm quite familiar with that issue, but that's not the case here. Running
out of NMBCLUSTERS can happen with any NetBSD machine, not just under Xen.

I can only reproduce my current problem under Xen. I've tested versions
from NetBSD 3.1 through -current (last month).

I don't remember that being the case the last time I had the NMBCLUSTERS
problem. Did you try sending the console break sequence to see if you
could get a DDB prompt?

I never run with less than 8192. Most of my machines are 2-4 times that.

Thanks.
