Except that right now, I can't even get through a 'make world'
without it crashing :( The only thing that I can think of is that it has
something to do with my re-arranging (ccd) my news spool, but then I
wouldn't have expected to get an error in sockets, I wouldn't think...
would I?
I got another crash after upgrading the kernel, this time looking
like the following. I would suspect swap space, based on it being in the
vm_ code, except that I haven't added or removed any swap space in several
months:
# gdb -k kernel.Dec30 vmcore.10
