But among the ports on which X11 depends is dbus, and dbus-daemon was one of the processes that was apparently spinning in CPU without evidence of accomplishing much of anything, so the X11 environment wasn't usable. (I was able to login to and use a vty on the laptop, though.) =20 Peace, david As was my HOME server which does NOT do ANY DNS services (It=E2=80=99s a DNS Clie= nt, DHCP Client).=20 It was with PostgreSQL starting and I also noted Exim, SSHD, and others spi= nning. Lots of NO BUFFERSPACE in a truss.=20 I suspect it=E2=80=99s related to UDP changes in the system.=20 =20
