Ok, I'll stop looking at that one.

Re-reading the slapd-hdb man page again, looks like the cachesize 
defaults to 1000 and the idlcachesize defaults to 0.  The man page 
suggests that the idlcachesize should be at least 3x the cachesize. 
Does that guideline hold for accesslog DB as well?

As an aside, researching the past 30 days of nightly updates, I find 
that the 32000 updates that happened yesterday are abnormal (happens 
only at semester change -- so, four times a year).  The normal number of 
updates is in the 200-2300 range (the average being 842, the median 
being 806).

So, I'm thinking something along the lines of a cachesize of 5000 and 
idlcachesize of 15000.  Does that make sense?

Thanks,
