I grant that this may be a complete red herring, but your description below  - not available and having to reboot - 
might have another explanation.  At least in Linux.

I have found that if you have a broken thread, and you try to access that thread, the daemon goes into an endless
loop and
I could not kill off the daemon by normal means, but had to reboot the computer.  The daemon cannot cope with not
finding 
an entry where one is referenced by a subsequent (or previous, I assume) entry.

A broken thread can occur if you move a thread with a large number of subsequent entries - more than say 50 (I
don't know 
the precise number) from one log book to another.  The copy part of the move works, but the deleting of the entries
in the 
original log book is incomplete, leaving an orphan set of (later) entires.  Access those, and it's time for a
reboot.  Which makes 
finding them a potentially tedius and multiple rebooting exercise.  I know, because I've had to track a number in
my time.

Just a thought.
