These are still showing over 47K IDENT lookups.

Probably you did not disable all the uses of IDENT. You need to both
set "ident_access deny all" and remove use of ident type ACLs.

Before trying that though, I attached a new patch to bug report 3803.
Can you apply that and see if it works?

NP: For your request rate of 150 req/sec I expect the mgr:mem "cbdata
IdentStateData (17)" to show less than 3K in "(#) Allocated" ( 12152
in "(KB) Allocated").
