I would also like to know. I've had cases where Data.fs.index hasn't 
been touched in several days (the modified time stamp shows a date 
several days ago), on sites that are very active (in other words, its 
unlikely that nothing changed). If I then restart the zeo, I find that 
it takes a very long time, perhaps because it needs to reindex.

I usually delete the old .index file (which appears to be stale) so that 
it can create a new one. Something happens and the zeo server stops 
writing to Data.fs.index. Unfortunately this very vague description is 
all I have right now, I've done no deeper investigation yet.
