The exact timing of the issue is to strange is there a backup job
running at midnight. Or some other timed job that could be eating the
ram or disk IO. Possibly one that is reliant on ldap queries that
would otherwise be inocuious.
It is possible that it is the tombstone reap thread, which runs
periodically. Do you do a lot of entry deletion operations throughout
the typical day?

Of the 7 replicas, 5 are attached to one network, and 2 are on

were getting
when I was using previous versions of the LDAP server.
The 2 that are barely used I've checked for excessive queries
being run
at the point when load goes crazy and they are getting the
usual minimal
load.
Also that doesn't explain why it's always 24 hours that it goes
haywire. It doesn't matter when I restart the service, it
could be
restarted at 2am, then in 24 hours it will go crazy IO load.
do you know what the IO is? is it swapping? are you running
collectl or similar so you can look at historic performance data?
