Are you using shm keys with BDB?

I don't know anyone who is using BDB 5.3 at this point in time.  I would 
back down to something less recent and see if you see the same issue.  I've 
used BDB 4.7 for quite some time w/o issue.

Also, your BDB cachesize seems undersized, given the size of your DB.  It 
should be no less than dn2id.bdb + id2entry.bdb + 10% for growth. 
Personally, I prefer to keep my BDB cachesize at <size of DB>, or in your 
case, I'd set it to 2 GB, i.e.:

set_cachesize 2 0 0

You certainly could try switching just this one side to mdb, and seeing how 
it does, and then switching the other side over if you like how it is 
performing compared to BDB.  Both nodes are not required to run the same DB 
backend.
