Mike,

Thanks for the suggestion. I'm pretty sure I have done a full fsck,  but
not positive, so I will try one tomorrow. The system is in a location
which is unmanned today due to the holiday, and a full fsck kind of needs
either a human or remote console. 

I have tried both with and without snapshots, so those don't seem to be
the problem.

In any case, I'll know more tomorrow.
