NetBSD/i386 5.99.64 locks up while running "/etc/daily"

        Hello,

my NetBSD/i386 5.99.64 virtual machine (VMware Fusion 4.1.1, 6 virtual cores)
locks up reproducably while running "/etc/daily". This is what "top" says
when it happens:

load averages:  0.00,  0.01,  0.02;               up 0+00:15:47        21:55:00

I've managed to enter "ddb" but the current process isn't doing anything
interesting. I've tried "machine cpu 4" followed by "bt" but CPU 4
is only in the idle loop.

Any ideas what to try next? This virtual machine worked fine with
NetBSD/i386 5.99.60.

        Kind regards
