Yes, and because of this I've taken it offline for now.

It got itself into a very strange state I've never seen before. Because no more 
filehandles were available, no program could run, because they could not open 
the basic system dylibs they required. The GUI failed, and not even the sudo 
command worked, so I could not shut it down cleanly and had to power it off.

Booting from the High Sierra install disk, Disk Utility's first aid reports 
that the main disk is ok.

It does not seem to boot up correctly now. The black startup screen with white 
Apple logo and progress bar filled all the way in never disappears. I'm not 
certain if all the usual services have started up correctly.

I can ssh in. I deactivated all the ports that had been left active. Many 
ports' files were still present and had to be removed by forcibly activating 
and then deactivating the ports. I think I got them all.

I will need to do some further investigating.
