Yes, that was wat I was babbling about wrt "syncing".

A reboot solved my problems -- while examining this phenomenon PostgreSQL
came to a halt and wouldn't restart due to a lack of available shared memory,
although ipcs(1) didn't show any active handles. Since I needed the database
server, I had to reboot.
I suspect something hardwarish though, I've never seen this kind of weird
The rain it raineth on the just
And also on the unjust fella,
But chiefly on the just, because
The unjust steals the just's umbrella.
